Option on in run-script doesn't always work

[Zoolander]

I have a strange problem.  I have it scripted so that when a certain dialog option is clicked, it will trigger another dialog option to turn on.  I have this in a dialog option.  It's scripted so that about 6 different options include the run-script that will cause this to happen. 

The problem is that 4 of them work the way they should.  But there's 2 out of the 6 options that include the same run-script number for option-on like all the rest, but will not engage that new dialog option to appear.  I can't find anything wrong with it.  Might there be a reason this happens?

If the option is in the current Dialog, you could try using the option-on dialog script command instead of run-script.

Otherwise, could you post your script? (Dialog and dialog_request) Kind of hard to tell if there's anything wrong, without seeing it.
