Total Type: Custom

[walter.dasilva]

Hi All,

How to make a a custom total to sum a expression like this Choose(TEV:TipEve=1 Or TEV:TipEve=2,FFI:ValEve,(FFI:ValEve*(-1))).

if i set to sum the code is: loc:total[n] = loc:total[n] + field, but if i set to CUSTOM the code is different as if i must have my own total variable...

is it right? how to this?
thanks
