correction of formula please............
 

C2=IF(A2+B2=0,"0",C1-A2+B2)

the above formula is which im using presently. then i came out with the one
below to eliminate the error which would occur by entering data on both
cells, A2 and B2 at the same time.

C2=IF(A2=0,C1+B2,IF(B2=0,C1-A2,IF(A2 AND B2=0,"0","ERROR")))

what i need to do is if A2 and B2 has values at the same time to show an
error message.appriciate if someone could correct the above formula.

See reply to your earlier post.
