Bind label text to a Client Tag to be used in Template Repeater

I have a label that I use expression binding to bind its text to an index of a Dataset. This index is a custom property on a template and when the template repeats, the index goes up and I get a new value for my text label.

tag(“Procedures/Procedure_List[” + {Procedure Box.index} + “]”)

I am trying to do the same exact thing, except the tag is a Client tag and I can’t seem to get to view the text on my label.

tag("[Client]Procedures/AllProcedures[" + {Card.index} + “]”)

I am having a tough time finding the documentation that would help me on this. Any help is appreciated!
