When I run this code I input BBB in cloth type and I insert numbers in input qty and it did not automatically multiply in 14.15 but no errors encountered. The reason why I need to automatically multiply it because the user input numbers where is the unit of measure is Frame I need to convert it to Dozen so I will multiply to 14.15 if NW and 15.85 if W.
