I am not sure if this can be done are not. But here is what I want to do.
I have a repeating table with a column that is a customer type that is populated from another sharepoint list.
Based on the type of customer I want to display/hide some additional form controls.
Some customers can have more then one customer type.
I tried creating a list box control and populated it for the values of the customer type for the selected customer and it shows all the customer types and the first line is blank.
So then I set a condition not to display another control if this list box contained one of listed customer types.
Since the first line is blank it thinks there is no customer type so nothing gets displayed.
Does anyone know how I can do this?. I am thinking I need to populate a text box and concantonate all of the current values so I can check to see if that control contains a particular customer type.
