Checking if Text Lable is empty

I am passing through some data form another screen to populate a text value. I am trying to add an if statement to only update the value if it is empty.

If(IsBlank(PlantTextValue),varPlant)

When I write this statement and put a period , nothing pops up like .text or .value. Is this correct for a text label? Or is there a better way to check if it is empty.

You should put it in the Defaults property:
If(IsBlank(Self.Text),varPlant)
Is there any way, that this field can be prepopulated from somewhere? otherwise you can just put varPlant in the default property.

it was originally created as a choice in a SharePoint list and then I added in a text Lable.

Okay that's why you're getting this error. it expects another Choice column.
Is your Variable also inside the Choice column?

The variable is set in a onSelect on a Button using the Set() with a variable from a combo box.
