Add the following attribute on your validated control

onblur="javascript: return validateAmount();"

somewhere on the page add the following:

function validateAmount() {
var lbl = document.getElementById("yourlabelID");
if (lbl != null) {
if (lbl.value > 20000) {
alert("You may not enter the amount above 20000!");
return false;
}
}

return true;
}

if you use jQuery you can replace getElementById with $("#yourlabelID") and lbl.value with lbl.val()
