I took a look, I’m afraid you’re REALLY over complicating it 
If you wanna know why your version wasn’t working, here it is in a nutshell:
-
First of all, you need to bind those boxes in the FloorPlan widget to integers like I showed you.
-
Then when you cast to the FloorPlan in the Table widget you have to set the correct integer in the FloorPlan, although I have no idea how you will know which one it is, because you don’t know which button on the FloorPlan has called the drop down.
To stay in the same widget you can use the table button to increment the number shown on the table. I did the first 3 tables like this:
The increment function:
Custom event:
It works just fine, but once again I bound the textboxes to integer variables like I showed you in the example project.
If you do it this way you don’t need ANY of those booleans or macros.
Then all you have to do is save everything in a savegame, so it’s the same when you open it back up, but that’s for another day…
