K, I have a drop down box in "Tracking" workbook B3 with "Part Numbers".
When I choose one of the part numbers from that drop down box I want C3
("Current Balance") to update with a value from my "Inventory" workbook.
"Inventory" workbook only contains column A: "Part Number" & Column B:"Qty
in Stock"
