/*************** Multiple Scripts If you have two or more scripts that use the onload event, probably only one will run (the last one). Here is a solution for starting multiple scripts onload: 1. Delete or comment out all the onload assignments, onload=initScroll and things like that. 2. Put the onload assignments in the body tag like in this example, note that they must have braces (). Example: **************/ function numbersonly() { if (event.keyCode < 48 || event.keyCode > 57) return false; } function numbersandpointonly(){ if (event.keyCode == 46) { return true; } if (event.keyCode < 48 || event.keyCode > 57) return false;
