error when trying to set multiple list validation formulas inside my custom list Validation Settings

Question

I want to add these validations to my list:-

1. if the status= "Invoiced", then user must enter a value inside the "Customer Invoice Date".
2. if the status = "Paid", then the user must enter a value inside the "Customer Paid Date"

now i tried addign these formulas inside my list validation:

=IF(Status="Invoiced",IF([Customer Invoiced Date]<>"",TRUE,FALSE),TRUE)
=IF(Status="Paid",IF([Customer Paid Date ]<>"",TRUE,FALSE),TRUE)

but i got an error:-

The formula refers to a column that does not exist. Check the formula for spelling mistakes or change the non-existing column to an existing column.

Now if i add each formula alone,they will work, but having them together will not work.. so is there a way i can add multiple validation for my list?

Answer 1

Use OR to combine the two formulas.

You can try that:

=OR(IF(Status="Invoiced",IF([Customer Invoiced Date]<>"",TRUE,FALSE),TRUE), IF(Status="Paid",IF([Customer Paid Date ]<>"",TRUE,FALSE),TRUE))

If it doesn't work, you can also use your formula:

=IF(Status="Invoiced",IF([Customer Invoiced Date]<>"",TRUE,FALSE),TRUE)
=IF(Status="Paid",IF([Customer Paid Date]<>"",TRUE,FALSE),TRUE)

And when you type the formula, DO NOT copy the formula and paste it, just type it one by one manually.

You can only have one formula. You have to combine the two formulas so that combined they return a true or false.

=AND( firstCondition, secondCondition )

Both must return true for the AND to return true.

=AND( IF(Status="Invoiced",IF([Customer Invoiced Date]<>"",TRUE,FALSE),TRUE),
IF(Status="Paid",IF([Customer Paid Date ]<>"",TRUE,FALSE),TRUE) )

But I think what you want is this:

=OR(IF(Status="Invoiced",IF([Customer Invoiced Date]<>"",TRUE,FALSE),  FALSE  ),
    IF(Status="Paid",IF([Customer Paid Date]<>"",TRUE,FALSE),  FALSE  ))

as you want Invoiced and a date or Paid and a date. If either is true, then the column validates.

Here's a shorter and cleaner version using just AND's and OR's:

=OR( AND(Status="Invoiced",[Customer Invoiced Date]<>"" ), 
     AND(Status="Paid",[Customer Invoiced Date]<>"" )
   )

And if the item is OK if Status and both dates are blank then:

=OR( AND(Status="Invoiced",[Customer Invoiced Date]<>"" ), 
     AND(Status="Paid",[Customer Invoiced Date]<>"" ),
     AND(Status="",[Customer Invoiced Date]="",[Customer Invoiced Date]="" )
   )
