I have 2 Lists of Data on the same sheet

List A is detailed in Columns A-D

List B is detailed in Column G-K

What I want to do is compare certain Columns/Rows in both Lists and for each one that matches, place an X in Column E (covering List A) and a corresponding X in Column L (covering List B). Note the matched values will not be on the same Row in both

So what will be compared? if Col B & D rows matches somewhere with Col H & K an X is placed on the appropriate Row in Cols E & L

Essentially I want to do a Supplier A/c Reconciliation. Above would give me a good start point
