Hey,
Interesting code 
I think it might find you get more responses if you copy & paste your code in, rather than linking a dyn… you can use the <./> button to help format it 
I think part of the problem is in the question… There isn’t any commenting in your code, so both you and I are finding it a little hard to spot the errors… Personally I also don’t break out code into definitions until I’ve got it working, because i find it hard to de-bug. Once you’re ready though, it’s a really great practice 
From what I can see, at first glance, I think the problem is this line…
for i in nameviews:
I don’t think you want to iterate through several views, you just want the index of the one which was selected? Perhaps? 
Best of luck,
Mark
