hi @RJ_Southam,
Your formula is correct as long as the field with the date of birth is called DOB.
I would possibly modify it to this: If(DOB<=12/31/2017, :star: ,"") if you want to actually have a blank field when the condition does not hold instead of a field with a space.

Hope this helps!

Actually the original formula had several issues.

• Emoji are characters and need to be enclosed in straight quotes.

• Hardcoded date strings need to be enclosed in straight quotes. As written 12/31/2017 is a mathematical expression that evaluates to about 0.000191917091816.

• It is also better to compare text strings with text strings rather than hoping that Airtable will correctly do data type conversion.

• it is better to completely omit the third parameter than to include a text string of one space or an empty text string.
