Calculate % complete based on a number in one cell - 4 cells should match the one.....

Trying to calculate the % complete based on the total (each has a countifs formula) in each cell:
"
# of Scripts Entered into HPQC # of Scripts "Ready for Pre-Approval" # of Scripts QA Approved # of Scripts WITH PQ Tester Name


Each of the above cells total should match the "# of 'Formal' Scripts to be created" cell and calculate the % complete based on the total number completed (see attached example).

I'd prefer not to have a VBA as loading the spreadsheet in a foreign country is difficult because of bandwidth.

All assistance is greatly appreciated.
Thank you!!!
