I know #DIV/0! is a common error but I can't seem to make my formula work
with the ISERROR statement.

My formula is returning a 0/0 value

=IF(I26,(G26+H26))/(I26-F26)


What am I doing wrong in this error correction statement

=IF(ISERROR(I26,(G26+H26))/(I26-F26)),0,(I26,(G26+H26))/(I26-F26))


It keeps telling me I entered too many arguments for this function. What am
I doing wrong ... or is there another way to do this ?
