<SCRIPT LANGUAGE=”JavaScript”>

decallowed = 0; // how many decimals are allowed?
if (isNaN(fieldValue) || fieldValue == “”) {
alert(“Oops! That does not appear to be a valid number. Please try again.”);
fieldName.select();
fieldName.focus();
}else {
if (fieldValue.indexOf(‘.’) == -1) fieldValue += “.”;
dectext = fieldValue.substring(fieldValue.indexOf(‘.’)+1, fieldValue.length);
if (dectext.length > decallowed){
alert (“Oops! Please enter a number with up to ” + decallowed + ” decimal places. Please try again.”);
fieldName.select();
