Embedded images based on a boolean

I'm making a table, and based on a variable in a specific row, I want to display one of two embedded images, icon_good or icon_bad. I'm currently using IIf (Fields!IsCompleted.Value, icon_good, icon_bad) as BackgroundImage.Value, but it gives me errors, and the type field refuses to fill itself in no matter what. I've tried google searching and searching here on the forums, and I can find info about embedding images, but not how to selectively show them. Hopefully this is just a simple trick and I'll be able to get some quick help here.

Thanks in advance

Hi,
Did you try with "".
IIf (Fields!IsCompleted.Value, "icon_good", "icon_bad") as BackgroundImage.Value
