Conditional Formatting with multiple conditions

Hello! I'm in need of your expertise!

On the Customer Summary tab, I need columns H and Q to have conditional formatting (highlight red with dark red text).

Here are the conditions:

Columns A & C need to be matched to the 'Cust #' and 'Dept' on 'Store Volume code' tab (Columns B & D), with the conditional formatting to be based on the values in Column E (less than or equal to).

Thanks in advance for your assistance!
