After execution, the following error pops up. Please help me to remove this error. I just want to get input from Entry field when the user clicks on 'Submit' button. I tried passing the StringVar() variables v1, v2, v3 and v4 as method parameters but that gave me error too. So I am stuck at this point. Any help will be appreciated.

P.S. I dunno why this was reported as duplicate. The mentioned question's answer does not apply to my question. I am not able to access the Entry widget to input user data.
