Best Way to select multiple values on single click?

[SetiRich]

Imagine a spreadsheet or array or ??? with a row of labels / codes at the top, and a row of labels / codes at the left. I populate this (right now, it's a listbox that has it's rowsource set with a dynamic query constructed in VBA), and the user selects a row / column by clicking.

Many of the row/columns are blank/null, so can't be selected. Whatever is selected, I want to return the two values from the row/col header labels. Sounds simple enough, but it's not apparent to me. Listbox's have no "column clicked" param...that I've seen. This is in ACC 2000.

Thanks for your insight,

Rich
