Hi

I have a bunch of codes that need the last digit changing but auto fill is not recognizing the change.

For example
09WWB2LIDSR
09WWB2LIDSS
09WWB2LIDST
09WWB2LIDSU
09WWB2LIDSV
09WWB2LIDSW
09WWB2LIDSX
09WWB2LIDSY
09WWB2LIDSZ

Only the last letter is changing but when I try and pull down from the first three it just repeats them...

Help would be much appreciated!
