[paulyeo11]

Hi All

I try to use the below expression :-

(

$(vOtherIncomeYtd)

-

$(vOtherIncomeLy)

)

$(vOtherIncomeLy)

I get null value , may i know how to make it display -64% ?

I notice that when i use below expression with bracket , it start to display null value.

(

$(vOtherIncomeYtd)

-

$(vOtherIncomeLy)

)
