crystal reports - If number is not null -

i have function returns last instance of "percent" field last few values null. need not include these null values , return recent/last not null value. have changed setting default values null , {command.percent}<> 0.00 still returns 0.00

sounds job isnull()

configure shared variable store latest value passes through it, only update value when not(isnull({yourvalue})). when reach end of report, you'll recent/last nonnull value.
