I have made the combo box. and I have also managed to list the details in
that box.
When I select the values form it, I want the row number of the value that I
have selected. When i mean the row number, I mean the rowmnumver from wher I
have sourced the data.

Basically, the first value that i select should display the value 1 next to
the combo box. I am using this column number to generate in interactive chart

Your help will be highly appreciated.
