Hey all

A mate of mine is following a system, and he wants to back the horses in six horse all ups, parlaying all the doubles, trebles, quads, fivers and the six horse all up within it.

Within six bets, there are

15 doubles
20 trebles
15 quads
6 fivers
1 six

He wants to have a set amount on the doubles, and less on the others. Not sure how much, it might be $20 on each of the doubles and $10 on all the others.

He has asked me to write a spreadsheet for him, and I just started, but it's a bit of a task for a novice like me, so I was wondering if anyone knew of a spreadsheet already in existence which would work these bets out?

Thanks.
