[Closed] My script – MaxProject and Rollout Close Error

I wrote a maxscript which would load at startup and pop a dialog to create a project folder etc [Just like a VC++ project] or to just open last opened file.
The script is attached.
Only problem is when I load it from run script, it works ok and exits. But when I copy to the max startup scripts folder and it runs automatically, it gives an error on exit –

>> MAXScript Rollout Handler Exception: – Type error: closeRolloutFloater requires RolloutFloater, got: undefined <<

Anybody got any ideas? why is this happening
Thanks
I’ll post the updated version, if I fix this problem.Any other suggestions are also welcome
