Excellent Pete, well spotted

not sure you meant to include the negative signs though.

Many thanks

Your problem is after the first 1000, as you are trying to have
another parameter after the false argument of the IF. Try this
amendment:

=IF(ISERROR(VLOOKUP(K16,pr,3,FALSE)),if(iserror(VL OOKUP(K16,nonpr,
3,FALSE)),"",VLOOKUP(K16,nonpr,
3,FALSE)*1000),if(iserror(VLOOKUP(K16,nonpr,3,FALS E)),-VLOOKUP(K16,pr,
3,FALSE),VLOOKUP(K16,pr,3,FALSE)+VLOOKUP(K16,nonpr ,3,FALSE)-*1000))

Hope this helps (and that I've counted all the brackets correctly)

Pete

I get an 'you've entered too many arguements' error message with my formula
below. What do I need to do to get it to work?

I have 2 tables, PR and nonPR, and I want to add values together where the
left most strings match in each. If only one table contains the string
then
take that value, if neither do then return a blank.

=IF(ISERROR(VLOOKUP(K16,pr,3,FALSE)),if(iserror(VL OOKUP(K16,nonpr,3,FALSE))-,"",VLOOKUP(K16,nonpr,3,FALSE)*1000,if(iserror(VLO OKUP(K16,nonpr,3,FALSE)),-VLOOKUP(K16,pr,3,FALSE),VLOOKUP(K16,pr,3,FALSE)+(V LOOKUP(K16,nonpr,3,FALSE)-*1000))))- Hide quoted text -
