hi
i want a formula that i can assign the M and N letters to nimbers 7 and 12 that i write M in one cell and in otthers it gives me the number also it sums that amount of cells
i did the first part with if condition but i dont know how to make it get the letter M and uses the number 7 instead of it
i explain it more
if i put M in cell A1 to A10 give me Number 7 for each one and in cell A11 combine them all for me but minus 10
