U r using software or utility

Excel utility

enable  macro by cliking the  yellow bar on top of  form

Go to your file 

press "validate" button on each and every page  you  have  entered data, if anything  is missing in sheet it will display, ask to enter then will validarte 

After  validation,  press calculate tax, dont enter the  tax amount with own 

after  this the error will not not  appear
