Formula to ignore empty date field

[Amy_Schrock]

My current formula works. IF({Post Date}<{Today’s Date},‘READY’)
But if {Post Date} is empty it is also saying ‘READY’
What should I add to the formula that ignores a field if it is empty.

One way to do this would be to wrap that IF statement in another IF statement:
IF({Post Date}, IF({Post Date}<{Today’s Date},‘READY’))

You could also simplify this by using TODAY(), which would remove the need for the field {Today’s Date}:
IF({Post Date}, IF({Post Date}<TODAY(),‘READY’))

That didn’t work. It gave me this message.
Sorry, there was a problem saving this field. Invalid formula. Please check your formula text.

I think the formatting of the quotation marks may be getting screwed up by the Code formatting on the forum. Try deleting and rewriting all the quotation marks, so they are plain text.

It worked. Thanks for your help.
