[thelist] else?

[David Lindblad]

Can anyone provided direction as how to end/correct this script, if a  
value of 4 or greater is entered I want to leave everything as is,  
anything less than four I require the message, as per script below,  
and the field entry to revert to empty.

var a = this.getField("quantity.0");

if (a.value <= 3);
event.value="";
app.alert("A minimum quantity of 4 is required", 4);

else???


Any advice would be greatly appreciated.
