Error when accessing Lookup field value

Posted on by Community Power Pla... Microsoft Employee

I am trying to conditionally mark a field as required if nothing is selected in another lookup field.

But it seems, that I cannot even correctly access the value in the Lookup field.

This is my check:

If(IsBlank(DataCardValue1.Selected.Value), True)

The (translated) error I get is: Unexpected characters: Formula contains "error", but "ParenClose" is expected.

It doesn't work with any condition (for example this gives the same error):

If(DataCardValue1.Selected.Value = "1", True)

Thank you!

Because you're using "True" rather than just true.

Try just:

IsBlank(DataCardValue1)

Remember, the above evaluates to true or false, so your original statement would effectively evaluate to:

If(true, true)

Therefore, you don't need the "if true" portion. Not that it would affect anything, but this is just a good way to keep your formulas clean
