>The previously suggested code should work. Of course you would use the backcolor property instead since text that isn't there doesn't have a color (What is the sound of one hand clapping Grasshopper?) The fact that it isn't makes me wonder which event your putting the code in, and if it's being fired at all?

I was hoping that was it, but I did have it in the backcolor one.

What do you mean by "which event"? As far as I know, it's a property, not an event. As to when it is evaluated, the docs say when the grid refreshes.
