Hi, Proberbly something simple, but i have no been able to find an answer.
I have a value in a cell, i want this to populate a combo box with values from another sheet, the cell value is an engineer number, i need to use this to sort from another list the customer name and display all the customer names, i have 30 engineers and 4500 customers to sort.

Any idea on how to do it ?
Many thanks in advance
