[QUOTE="116, post: 3970397"] I have this script to maintain a 4 character entry done with a hidden field, but i have an issue with people putting leading zeros. How can I have an alert when a leading zero is entered and exit the script? <script> function sortdashno() { with (document.forms[0]) { { if (DASHNO.value.substr(0,1) = 0) alert("Please remove leading ZERO"); else if (DASHNO.value < 10) DASHNOSORT.value = "000" +DASHNO.value; else if (DASHNO.value > 10 && DASHNO.value < 100) DASHNOSORT.value = "00" +DASHNO.value; else if (DASHNO.value > 100 && DASHNO.value < 999) DASHNOSORT.value = "0" +DASHNO.value; } } } </script> Thanks David [/QUOTE]
