I have two columns that wish to validate on. Column A is a number field and Column B is a choice (drop-down) field. I wish to restrict the options that can be selected in Column B if the number entered in Column A is less than 8. Is this possible please?

1 Answer 1


Yes. This can be done something like below

=IF([ColumnA]<8, IF([ColumnB]='Option1', true, false), true)

If columnA value is less than 8 it check if columnB value is option1 then return true else return false else return true

Similarly you can nest all the other option values that need to be validated

  • That worked perfectly - a problem I have been unable to solve for the last 2 hours has now gone away. Thank you!
