Hi is there a way to only allow a certain numeric amount to be entered into a text input? i.e, Like nothing over 20?

Thanks

Well, if we are talking about one textbox only it is simple:-


<input type = "text" id = "mytextbox" size = "2" maxlength = "2" onblur = "chk(this)">

<script type = "text/javascript">

function chk(which) {
var val = which.value;
if (val > 20) {
alert ("The maximum value allowed is 20");
which.value = "";
setTimeout("document.getElementById('" + which.id + "').focus()", 25);
}
}
</script>
