Welcome to sc2mapster! Feel free to send me a PM if you have any questions or concerns :)

This error means that you're trying to hide the dialog box, but it can't find the dialog that you're asking it to hide. My guess is that you used "Triggering Dialog" or "Last Created Dialog" here, which would cause this error.

If that's the case, you'll need to assign your dialog to a global variable, and then reference that variable later. For example:

// Dialog Creation Trigger
Create Dialog with offsets (whatever) anchored to (whatever) with size (whatever) // You already did this part
Set Variable (My Dialog Variable) to Dialog (Last Created Dialog) // This is the line you need to add, so sc2 can remember which dialog is which for later

// Now when you need to hide the dialog... 
(Hide) Dialog (My Dialog Varaible) for players (All Players) // We tell it to hide the dialog we saved in the variable earlier

If you can't figure it out, please post a screenshot of your trigger. It's a bit tricky to diagnose the problem without seeing the trigger itself.
