Greetings!
 
I am new to the forum so I apologize if my question is redundant!
 
I am trying to combine two "If" statements into a single formula.  I need smartsheet to look at two columns (Due Date) and (Project Completed -- checkbox) and determine if a project is late.
 
I can get each half of the formula to work individually, however, when I combine the two I end up with an "Missing or invalid parameters".
 
I would appreciate any help!
 
Here are the two individual formulas that work:
 
=IF((TODAY() - [Due Date]1) < 0, "", "Action Required")
 
=IF(ISBLANK([Project Completed]3), "", "Action Required")
 
Thanks,
