Hello,
I'm trying to increment using two criteria; Category (Primary #) and
Question(Secondary #). Categories will be 1, 2, 3, and the questions
that fall under each category will increment by 0.1 (i.e. 1.1, 1.2,
etc..). I'm using the formula B2+0.1. It works great up until it reaches
1.9, but after that, it jumps to 2. It should display display it as
1.10.

Ive attached a screenshot to illustrate what Im trying to do.

One more thing (Sorry lol), I've also noticed that 1.10 will display as
1.1 creating a duplicate. I'll be using these numbers as IDs, so it's
important that they're unique..

Thanks in advance for all your help

Your spreadsheet is calculating correctly based on the data you are inputting. Row 3 in your range already has the 1.1 value you want returned in Row 12. As you note, there is no difference in the numbers 1.1 and 1.10 so your calc would create a duplicate number anyway. Maybe you want to work in true hundreths instead of tens: 1.10, 1.11, 1.12, 1.13, 1.14.... 2.10, 2.11, 2.12, 2.13, etc.
