Hi ,
I have IG with columns 'Reserved' and 'Booked'. Total of these columns should not exceed to 'Total Capacity' field. When I update or insert the value to the IG Total(Reserved+Booked) should be calculate and validate against 'Total Capacity' field.
Now I am trying to calculate total using JavaScript but it getting calculated on stored in the hidden itemonly if you tab out. If you don't tab and click on Save then the validation will be failed.
