Being a nubie, I looked through the w3schools website for the coding information and tried to use it, but for some reason it isn't working. It only picks up the cost as 4.25. Can someone tell me what I'm doing wrong? :) <HTML><HEAD><TITLE>Price Adjust per Quantity</TITLE><script LANGUAGE="JavaScript"></SCRIPT></HEAD><BODY ><TABLE BORDER="0" CELLSPACING="0" CELLPADDING="0" width=600><TR><TD valign=top width=150></td><td valign=top><BR> <BR><FORM name="order"><table border=0><tr><td>Quantity: </td><td><INPUT NAME="QUANTITY" TYPE=Text></td><td><INPUT TYPE=Button VALUE="Confirm Quantity" onClick="priceAdjust(this.form.QUANTITY.value)"></td></tr><tr><td>Cost:</td><td><INPUT NAME="PRICE" TYPE=Text></td></tr></table></FORM><p><br><p><br><p><center><script> function priceAdjust(text) { cost= ""; QUANTITY = "this.form.QUANTITY.value"; if (QUANTITY <= 99) { cost = 4.25; } else if (QUANTITY >= 100 && QUANTITY <= 1000) { cost = 3.99; } else if (QUANTITY >= 1001 && QUANTITY <= 5000) { cost = 3.89; } else if (QUANTITY >= 5001 && QUANTITY <= 10000) { cost = 3.79; }// else if (QUANTITY > 10000) {// cost = 3.75; } else { cost = 3.75; } document.order.PRICE.value=cost; }</SCRIPT></BODY>

QUANTITY = "this.form.QUANTITY.value";

Strings (except the empty string) are always evaluated as 0, which is less than 99. The browser needs to see this:

QUANTITY = this.form.QUANTITY.value;
