Can someone point me out what is wrong with the script. I am just trying to get a conditional out-put from the script. It will wait until the Toggle value turns true.

Unindent this line, the OUT should not be inside the DEF.

Yes you are absolutely right about that. That was a stupid mistake. I have edited the script but still it’s returning an empty list.

I am still missing out something.

I don’t know what you exactly want but your script works fine by me:
