I use Excel 2003. I am doing a detailed analysis to make a "make or buy"
decision. I have a table containing columns QUANTITIES - BUYING COST -
MAKING COST. Data run into sevaral rows according to buying quantites and
related costs. I need to find out the "QUANTIES WHERE BUYING COST IS LOWER
THAN MAKING COST" to help my boss to decide at what quanties it is economical
to start buying.

I tried VLOOKUP / HLOOKUP /IF etc. nothing worked. I will be grateful if
any body help me to solve this problem?
