It is best to always show the entire error message including traceback.  
As text, pasted directly into your post, not as an attachment.

I see nothing in the code you provided which makes a "lineEdit_29" 
attribute, so on the face of it this error message is pretty expectable.

But conversely, I don't see anything in your code which tries to access 
such an attribute either.

So clearly there's stuff you haven't shown us. More information 
required.
