Sorry about the unclear specs before. This is the first time I have had to actually try to explain these type of directions to anyone.

Sometimes there will be duplicate numbers in each column. There cannot be any duplicate numbers per possible combination. No number will be equal to or less than the number to the left.

Secondly, I'm expecting to use numbers in all five columns. Any combinations found using less than five columns aren't allowed. Also, I anticipate up to six or seven numbers in column one. upto fifteen numbers in columns two thru five.

This means I am expecting some possible over flow of combinations onto a second worksheet (hopefully not a third).

Again thankyou very much.

P.S. Are there any good resources for beginners that I can get my hands on to read and teach my self VB. I'm sure this sight if full of useful informationk, I just haven't had time to look thru it all.
