 I have been trying to dynamically create my dialogs for awhile now with a fair bit of success. The first major hurdle I have come across is the above code with error. I am trying to create a dropdownlist and then add a handler to it so whenever the selected item is changed it runs a bit of code. Please let it be known that pass() is not my code, I put it in there as a placeholder because the string for my actual code is quite long. And with pass() in there it will still raise the same error as my real code would. I believe that it may have something to do with how its creating the definition from the string when passing it to the addRollout command. Somehow the definition string is not being written properly and its expecting a do in there somewhere and just isn't getting it. Has anyone else ran into this problem with the rollout creator? Thanks

Since 3ds Max 2012 you need to add an extra space to the parameter string, before the spaces were added automatically. Now it concatenates indexNum with do so it returns an error saying that instead of the expected do, open parenthesis was encountered. Just change it to paramStr:"indexNum "

That did it, working perfectly now. Thank you very much for your answer to my question. Cheers!
