Will not import data from google doc or allow me to cut and paste that data

Will not import data from google doc or allow me to cut and paste that data

Hi - I have successfully been able to create a new form previously by importing data from a spreadsheet. Tonight when I am trying this I select the document I want - press next and it says loading and then does nothing.  Same thing when I try and cut and paste info as an alternative - select paste and no entry is made.

Thanks
Kendra
