Thanks for the update! Ongame_Bet has a small bug because it wants to use the separator instead of the decimal char to input comma values.
<font class="small">Code:</font><hr /><pre>
Ongame_Bet(bet = "") {
global
ControlFocus, %Ongame_BetAmount%
if (Ongame_Separator && bet)
;StringReplace, bet, bet, ., % Ongame_Separator
StringReplace, bet, bet, ., % Ongame_Decimal
Bet(bet)
}</pre><hr />
