Date formula calculation acting like string

edited 12/09/19 in Smartsheet Basics

I am troubleshooting a formula using a help example.

My formula is in a date format cell and references a date format cell with a value of 03/01/18

=[DPP Start Date]49 + 5

The result is 03/01/185

What is wrong with my syntax?

    That is bizarre. And shouldn't be showing up like that. I would contact support and find out what is going on. When you say date formatted cell... Do you mean Date formatted column type? If you right-click on the column header, and choose Properties does it show Date or Number as your Column type? It should be set to date. 

  • Hi Mike, I meant date formatted columns. It is bizarre because when I try other calculations like =[DPP Start Date]49 + (30*0.4)  it returns an 03/01/1812.

    If I enter =[DPP Start Date]49 - 5 ir returns #INVALID OPERATION

    I will note that I am in a 30 day trial period of Smartsheets

    I would contact support and see what they have to say. I doubt that being on a 30day trial would be an issue.

    Is the column you are pulling the date from a Date Formatted column? 


  • The column where the formula resides is a Date Formatted column
