Thanks for help, I have tried, But still the same error
Have you checkes SalesM entry and after Sprice update the footer should update, but it gives error of RateofSalestax required, (because it is required in table) May you have tested with existing entry as there is already all entries in records, nothing empty
Oh, yes, I did not test on a new record and in that case, yes, you do get an error. That would be one of the reasons I don't do validation at the Table Level. So, they way to avoid that is to move the Requery line to After_Update of the required field. Not sure that will work either but it's worth a try.
