When I set next step in debugger to Else If or Else, FMPA then jumps to End If, and it doesn't matter if the calculation returns True or False.
How to replicate
Create the following script, and try to debug it:
If [ 1 = 2 ]
Else If [ 2 = 3 ]
Else If [ 3 = 4 ]
Else If [ 4 = 4 ]
Show Custom Dialog [ "OK" ]
Show Custom Dialog [ "Also OK" ]
Show Custom Dialog [ "Error" ]
Or use the test file I've attached.
Comment all Else If steps above the one you want to debug.
