Hi there guys I have a question. How do I put values on items in a comboBox and compute its total?
You can look at my attachment for your reference.
Normal Subjects are worth 2 units and Subjects with "-Lab" are worth 1 unit each.
Now when I check subjects in the combobox it automatically adds up the total of what I have checked to my total units textbox. How do I do that? Help me please... thank you
