IF formula for dates in the past and future

edited 05/26/22 in Smartsheet Basics


I need a cell to do the following:

If Cell B is dated past Cell A date, leave Cell C blank. (for example, Cell A is dated 1/1/23. Cell B is dated 1/1/24. I need Cell C to be blank)

However, I already have the following formula in Cell C:

=[Cell A]$51 + 60

What do I need to add to the current formula to do the above?

Thank you!
