[RESOLVED] Dividing 2 fields in your detail (Access)

Hi,

I got a report with a field "Retail_Price" and a field "Last_Cost", the field after that is the Mark up %. I would like to display in the Markup Field the Retail_Price divided by the Last_Cost. Does anyone know the formula that I would put int he control source of the Markup field?

Thanks

sorry, i couldnt understand the control source.
the formula, ofcourse you might be knowing "=Retail_Price/Lost_Code"
I am sorry if I am wrong
