Hi. I'm having trouble with a blackjack program I'm writing. I need to know how to prematurely end a sub.

My code is:

Sub cmdStay_Click ()

MyScore
PlayerAce (11,1)

StayClick = StayClick + 1

If SplitClick > 0 then
????????
Elseif SplitClick = 0 then
SplitScore
Endif

cpuDeal
cpuScore1

End Sub

The ??????? is the part I'm unsure about. Can someone PLEEEAAASSSEEE help me.
