I am working on a validation to determine if a selected choice is okay based off a previous selected choice.

There are a number of categories (labeled 1 thru 13). Category #1 and Category #13 can have Type N selected. The other categories (2-12) can have any type (N, S, V, O).

Both the Category and Type are Choice columns.

Current formula:

=AND(OR([Category]=#1,[Category]=#13),[Platform Type]=N)

Q1: Can I even use a choice column data type in the validation formula?

Q2: If so, what syntax is incorrect in my formula that is preventing it from saving.

Try changing your formula into this:


And to answer your additional questions:

  1. You can use choice columns in the validation formula
  2. You should just enclose the values you are comparing with in the double quotes.
  • I tried your suggested change and did not receive a syntax error, however, I received the following error One or more column references are not allowed, because the columns are defined as a data type that is not supported in formulas.

  • Please try using the different name for the Type column (and update the formula accordingly). Commented Mar 23, 2018 at 19:45
  • @cheshire Do you actually have a column named "Type". That's not a legal name. You should have seen this when you attempted to create the column: "The column name that you entered is already in use or reserved. Choose another name." Commented Mar 24, 2018 at 3:21
  • @MikeSmith-MCT-MVP My column is actually 'Platform Type', I should've realized this is an important distinction. Sorry, was trying to keep the info as generic and unidentifiable as possible. Will update question.
