Hi Frances

One way
=IF( COUNTA(G5,J5,M5,Q5)1,"error",
IF(COUNTA(G5,J5)0,W49*0,
IF(COUNTA(M5,Q5)0,W49*140%,"")))

I am using the following formula:
=IF(M5="x",W49*140%,IF(Q5="x",W49*140%,""))
but I need to change it to solve the following problem,

1. How can I use 4 cells J5, G5, M5, Q5, I need to insert a caracter into
any of this cells (at this moment I am using "x") But I really want to be
able to use any keyboard key for the formula to work.
2. using j5="x", w49*0,""
3. using g5="x", w49*0,""
4. using m5="x", w49*140%
5. using Q5="x", w49*140%
6. But the major task that I want accomplish with this formula is to allow
me to enter only one "x" (meaning I can only select ONE between J5, G5,
M5,
Q5)
