I have written some functions in VBA to calculate profit margin, cost and
suggested retail price. they are simple in that the RETAILPRICE function has
two arguments, COST and MARGIN. i am also using an argument named COST in
the PROFITMARGIN function. how can i get VBA to recognize these as seperate
variables? do i have to put them in separate modules? or is there a certain
way i need to declare the variables? thank you.
