Scott,
First you have give the user change to check it, this will only get a loop
and a crazy user. Probably you have seen those AVI's from a user jumping on
his srcreen and other like that.
So you set this in a windows.forms.timer (you can drag that from the
toolbox).
Start from the toolbox the event from that and set it to enabled when needed
and than an timer where you set the interval to 10 or something so it fires
direct.

Than in that event something as
mytimer.enabled = false
If Not RadBut4.Checked Or RadBut5.Checked Then
MsgBox("Please choose Annual or Single Trip")
mytimer.interval = 4000
'dont set it to low a user has to be able to do something, he has to click
this button and to set the button
mytimer.enabled = true 'when you dont do it like this it goes on
firing.
end if
I hope this helps?
