Adding 30 or 60 days to a date based on another Cell Value

I am trying to calculate either 30, or 60 days from a date, depending on the value of another cell.  Example:

Cell 1:  Date

Cell 2:  $ Value of less than 50k or $ Value of $50k and up

Cell 3:  Date plus 30 or 60 days, depending on the value of Cell 2.

Any ideas?

    Try this formula. 

    =IF(ISBLANK(Value1), "Please Enter Value", IF(ISBLANK(Date1),"Please Enter Date",IF(Value1>= 50000, Date1 + 60, IF(Value1< 50000, Date1 + 30

    • If your column names contain spaces use brackets like this... IF(ISblank([Value Name]1), 
    • These are based on row 1 - adjust the number to adjust which row you are pulling from. 
    • I left off the closing brackets as Smartsheets will close them all for you. 
  • I made an attempt, but it's coming back unparseable.  I've included a screenshot, but here is the string I used.

    =IF(ISBLANK([Project Value $]1), "Please Enter Value", IF(ISBLANK([Commissioning Date]1),"Please Enter Date",IF([Project Value $]1>= 50000, [Commissioning Date]1 + 60, IF([Project Value]1< 50000, [Commissioning Date]1 + 30)

    Thanks for your help by the way!

    Delete the closing parenthesis... Let Smartsheets close them all for you and see what that does. That should do the trick...

    If that doesn't work, make sure there are 4 closing parenthesis at the end. ))))

    You can also get by without the 4th IF

    =IF(ISBLANK(Value1), "Please Enter Value", IF(ISBLANK(Date1),"Please Enter Date",IF(Value1>= 50000, Date1 + 60, Date1 + 30)))
