I have inserted the Spreadsheet but having problems putting the headers, I want them to type in the fields below. If there is a better widget we could try then please let me know. 

Please help!!!!

The header texts (column and row) of the Spreadsheet widget can only be edited using custom CSS codes that will be injected into the widget — How-to-Inject-CSS-Codes-to-Widgets

That what was done to the other Spreadsheet widgets in the form you shared with us.

You can also try using an Input Table field instead to represent a table in your form.

I hope this helps. If you have other questions, please do not hesitate to let us know.
