In a text box, I need to show value as per the label name.

In one text box, I need to show value for Overdue label name, which is 1.
In another text box, I need to show value for next1, which is 2.
I tried below expression but it is only working for the first condition.
=iif(First(Fields!Label_name.Value, "DataSet1") = "Overdue", First(Fields!Label_value.Value, "DataSet1"), 0)
Please help.
