# Hide Invalid Data Type

How can I show the cells as blank until the data is entered? Currently getting a invalid data type until date is entered. I'm using =NETDAYS([Date of Last Contact]@row, TODAY(0)).

I hope you're well and safe!

You can add an IFERROR function at the start of the formula.

Did that work/help?

I hope that helps!

Be safe and have a fantastic week!

• Below is a screen shot of my smartsheet. I would like to hide the cells that have #Invalid Data. These go away once the data in the formula has been entered. I tried your suggestion but could not get it to work.

Here is the formula:

=DATE(YEAR([Last Oil Change]@row) + ROUNDDOWN((MONTH([Last Oil Change]@row) + Frequency@row) / 12, 0) + IF(IF(MOD(MONTH([Last Oil Change]@row) + Frequency@row, 12) = 0, 12, MOD(MONTH([Last Oil Change]@row) + Frequency@row, 12)) = 12, -1), IF(MOD(MONTH([Last Oil Change]@row) + Frequency@row, 12) = 0, 12, MOD(MONTH([Last Oil Change]@row) + Frequency@row, 12)), DAY([Last Oil Change]@row))
