harson, no problem but, basically, it is very simple to calculate: if the odds are -140 that equals your bet amount times 1.4, eg if you want to win $10 then you calculate the risk by multiplying $10 x 1.4 = risking $14 to win $10. another eg odds = -122 hence to win $100 you calculate by multiplying 1.22 x $100 = risking $122 to win $100. when play a dog just reverse the process. i hope this helps. bol
