I would truly appreciate and help. I have a form and prices are based on ''price break''. 1.The price break fields work fine, but I cannot for the life of me add more than one to a page. 2. Also need to add the two results to a ''total'' field. (See code attached).Rather than hard-code the form elements that the script checks, passthe form elements as objects to the functions. For example: <FORM name="someForm" id="someForm"><INPUT name="someTextBox" onkeypress="checkKey()"> function checkKey() {var txtBox = document.forms[''someForm''].elements[''someTextBox'']; // Do something with the text boxtxtBox.value} What I''ve presented above is similar to how you access the form inyour code below. It would work fine, but it can only access the hard-coded forms and controls. One could change it to this: <FORM name="someForm" id="someForm"><INPUT name="someTextBox" onkeypress="checkKey(this)"> function checkKey(control) {var txtBox = control; // Do something with the text boxtxtBox.value} Notice the function call and how the control is referenced. Thesnippet above is effectively the same: the variable ''txtBox'' refersto the same control, someTextBox. When the keyword, this, is used inan intrinsic event, it creates an object reference that representsthe control. You can then use that reference in the same way as youwould a fully-qualified one. This way, you can use the same functionon multiple controls. That will stop you from having to duplicate the same script, andallow you to use as many price breaks (whatever they are) as youlike. What follows are some comments on your HTML. <HEAD>You are using intrinsic events, but you have not specified thedefault scripting language. Include: <META http-equiv="Content-Script-Type" content="text/javascript"> here. Also, HTML documents required a TITLE element (and a DOCTYPE). </HEAD> <BODY onLoad="findPrice();"> <SCRIPT LANGUAGE="JavaScript">The type attribute is /required/ in HTML. When used, it renders thelanguage attribute (which is deprecated, anyway) redundant. <SCRIPT type="text/javascript"> This closing comment should be removed. </script><snipped duplicate script> <form name="Hypersnap" method="post">   <p><font face="Arial" size="2"><b>Number of Users Required :</b></font>Why use style sheets, but also include deprecated FONT, B, and badlayout techniques (non-breaking spaces)? <snip> <input type="text" name="hstotal" value="0.00" size="16"<snipped other attributes> language="JavaScript"> INPUT elements do not have a language attribute.
