Conditional formatting Vloolup/Match inside to change Colour

Good afternoon

I have been looking on the net to use conditional formatting Cant seem to find the right guide

I am trying to get Column A to look up its self the truck number and match it to Column j and M and going on the cell next to it the colour would change
Green for PIK Red for REL

I have tried to use =$N3="PIK" which was working Then I remember some times we have a truck that is not on the list so we add it in e.g. Truck 14A Truck3A in Column A

which then bugs out =$N3="PIK" and it changes some of the colours

I think I need to use a vlookup or a Match

Any help would be great

Good afternoon AliGW

You are the best did not know you could do 2 vlookups with inside the 1 formula
After getting this to work on my sample book I have changed all the cells to match my main sheet
=IFERROR(VLOOKUP(B1,'Pick order'!$L$4:$M$28,2,0)="REL",VLOOKUP(B1,'Pick order'!$O$4:$P$28,2,0)="REL")

Thanks again for all your help
