Question about global variables?

So I wanted to set a global variable that was the previous layout. Saved as a string. Set the var as a string=current.layout name. However, as an action, I can't change the string value to the current layout name.

Doing it as a numerical value works, but strings don't work. I'm sure there is a reason for this, but I'm not sure why.

It's ok, I can map all the levels to numbers, but I struggled with not being able to say layout = "Town"

Also go to previous layout isn't workable in this situation. Otherwise, I would use that.

I guess the question is why strings can be global vars but can't be changed from the event sheets...

Yes. I guess I didn't understand that global vars still need to be linked via the event sheets. I had moved all my globals into one sheet and when I included that on the layout it let me use a string. Dumb, Dumb, sigh.

Thanks

The globals can remain in one sheet so it must be a different problem. The events that modify the globals need to be on an event sheet linked(included) to the layout you are on.
