currently, I got some problem in doing my RTF Template.

the units field, im using expression '<?xdofx:if UNITSINCURRENTRUN = 0 Then UNITSINCURRENTRUN else if UNITSIN is null then 0 Else UNITSIN end if?>'

the problem is, when i want to make the grand total below the units field. I cant get the correct value for the sum.

Anyone care for help?

Thank you

already tried using <choose><otherwise> function but still not succeed
