This is what it is kickin out. The formula is as follows; =(C53*D53)*E53 Problem is D53 is calculated from another cell and comes up a decimal sometimes, but i have the number formating in the cell with no decimals to round up automatically. But the formula is still using the decimals? How do i make it use the displayed value, instead of the actual value? Thanks
