End Sub
The code that was created works perfectly however the coding ends where the ‘KS5’ section ends , is it possible to have the same code run through the sheet so that the same effect happens? however it must be dependant on the KS4grades/Effort and KS3grades/Effort toggle options respectively. i have also attached a spreadsheet which also conatins the coding used Attachment 131748

i dont really know how to write the coding for it and i have tried to edit it to work on the othere area nut it hasnt been succesful any help on this problem
