Hi,

I am trying to use auto fill to do a sequence like this instead of having to type many rows of something that is very repetitious:

ZCT150 5.0
ZCT150 5.5
ZCT150 6.0
ZCT150 6.5
ZCT150 7.0
ZCT150 7.5

ETC.

I tried a custom fill, but that does not do what I expected. It just does the same as the auto fill.

I'm thinking maybe a formula will do it, but I'm not sure how to build such a formula.

Any help is greatly appreciated!
