Totals feature can't count Sum on this field

[yohansetiawan]

I have a form on database sheet model that contains this fields:

-Product Name
-Price
-Quantity
-Totals =>> control source is ==>> =[Price]*[Quantity]

When I use Totals feature it can't count Sum on my "Totals" field that contain =[Price]*[Quantity] on control source.
It restrict me only can Count on this field, another field like Quantity nor Price is fine with Sum, Avrg, etc like usual.


How do I get Sum from this "Totals" field??

My problem solved with making query then attach it to form.
