I am using my view in a grid. I want to set the view caption in view fields property as follows:

IIF(BETWEEN(O_ord_pay.op_flag_1,8,9),"JV #","Invoice")

When I display my grid, the caption reads as

IIF(BETWEEN(O_ord_pay.op_flag_1,8,9),"JV #","Invoice")

instead of either JV # or Invoice. I'm I doing something wrong here?

Thanks
