I was given the following formula:
=C$5 & "@" & C$6 & " A, B, C"
However, I want it to be changed to the following formula:
=C$5 & "@" & C$6 & " A, B, C, D"
only when the data at the cell "C8" is equal to 1000 sec. and keep the
previous one when is 500 sec.

It is possible to do this?.

Thanks in advance.
