I have added the 8 after my actual coordinates already.
When I step on the switch, all I hear is the "water drop" sound that usually happens when the switch is stepped on.  That's it.

Something else I forgot to add that might help: When I step on the switch, it presses down.  But when I leave the room and come back, the switch goes back up and I can step on it again.  But still, nothing happens.  If I leave the room and come back again, the switch is pressable again, so on...

The Type 2's interaction coordinates are supposed to be where the chest appears, right?
Just in case I need to clarify:
It said above that Type 2 interaction ID 2117 is a chest that will appear when a switch is stepped on.  So I placed that on the map in the coordinates I want the chest to appear.  I placed an Interaction Type 8 over a switch tile and set the ID to 900 (switch that stays down when stepped on).  That's all the information I got in Fatories's post.  When Link steps on the switch, it stays pressed, but no chest appears.  Setting the Interaction type 2 ID to 2117 or 2000 does not work.  Maybe it's just because I'm trying to do this outside of a dungeon.  I haven't gotten to dungeon editing yet; I'm only experimenting with the overworld and caves trying to learn as much as I can.

I'm asking for it.  I've always wanted to make my own Zelda game after so many years of playing pre-made ones, and Oracle of Ages looked like one of the simplest places to start, maybe right after Zelda One.  The betas of ZOLE 6 already look so much better than ZOLE 4.  I'm doing what I can do with ZOLE 4 right now and when ZOLE 6 gets released, I'll be even happier.  I believe ZOLE 4 is the only Oracle of Ages editor out there, so one with more features and simplicity will definitely be a fantastic upgrade and will hopefully allow more people to make their own Zelda game.

I'm hoping to be the first downloader of ZOLE 6 when it's released.  Until then, thanks for the help, I'll try to check out the IRC channel, and good luck with ZOHS! 

BTW, do you need that error code I posted a few days ago anymore?  If not, I'd like to remove that post.

Okay, so I added a switch with ID 900 (type 8 interaction) and a chest with ID 2117 (type 2 interaction) but when I step on the switch, nothing happens.  I've noticed in a lot of dungeons with switches in a room, there's also a type 3 interaction pointer in the room.  Could this be causing any trouble?  Because I have no idea on how to use a type 3 interaction.

Also, it should be noted I'm trying to do this in a cave with Area ID 45, not a dungeon, if that might be a problem.

Not a problem at all, I'll live with it.  When I said "A button", I meant "any button", sorry.
I have one last question out of curiosity.  Is there any easy way to change what the people say after something happens, such as Link getting the sword or completing a dungeon?  Nothing all that complicated or I'm not interested.  Just wondering.

Great!  It works!  Thanks!
Unfortunately, there's still one problem.  I edited the text in ZOTE and went back to the ROM to test it.  I talk to the guy and he does say what I programmed.  I assigned him three lines of text.  At the end of the first two lines, the game waits for me to press A to keep reading, as usual.  But at the end of the third line, the text window goes away without me pressing A.  Is there a way to keep it on the screen until I press A to close it?  This isn't the biggest deal because it's still readable, but I'm just curious.

Cool.
When I downloaded ZOLE, it came with ZOTE, ZOSE, ZOCF, and GBHL.dll version 1.1 only.  Where can I download ZOTE and GBHL.dll v1.0?  The only thing I found links back to zeldahacking.ulmb.com.  I tried changing the link but it didn't work.

The only program I had the ROM open in besides ZOTE is ZOLE which is supposed to be.
Let me know when you don't need that error stuff anymore because I'd like to remove that post.

Thank you for the info!
I used the interaction ID 4101 with the old man who comments about "folk vanishin'" and I got him to appear on another map.  Yay!
Now I go to ZOTE and try to edit his text.  But when I'm done editing it, how do I save it back to the ROM?  If I go to File > Save in ZOTE, I get the Windows error message "Unhandled exception has occured..."

I'm hoping to make a small OoA hack and ZOHS looks like a fantastic program to do so.  I'll definitely be sticking around awaiting the release of ZOHS!

I am mostly a beginner with editing OoAges.  I know how to add custom enemies to overworlds and stuff like that, but how do I add people?  I want to place a person on an overworld (present or past) map that says something when you walk up to them and press A, same as the original game.  I'm assuming I have to use ZOSE but I don't know which commands or interaction color to use.  I cannot find a tutorial on this anywhere on the internet or included with ZOSE or anything.

And please don't link me to zeldahacking.ulmb.com.  I don't know if that site is down or what but I cannot access it no matter what web browser I use.  Thanks!
