Conditional Formatting

I would like a formula where Cell V2 turns red if cells in a diffrent document I18:I24, I28:34, I38:I44 (up to 504)>0 and if O16, O26,O36 (Up to 506) does not contain "DW".

I18:I24 corresponds to O26, I28:I38 corresponds to O26 and so on.

In other words if I cells i described above>0 but there is no "DW" for the corresponding then it will highlight the cell.

This is a purchase order form, so basically I want a conditional formatting for when there is a pending order that needs to be signed "DW". Ie quanity is >0 but not signed

Hope this makes sense, I have attached pictures of what the sheets look like.
