Javascript form with quantity conditional pricing

[simora]

Hi:

Need help with sample code to set pricing on Order form based on quantity, then, write out the unit price that is actually given. Here's my sample bit of code. Cant get a workable funtion to make 'getHVUnitPrice() work.

<P><font color=""#FFA0CC" font size="2" face="Verdana">

Here is the break down;<BR>
<P>

0-99: CANT TAKE YOUR ORDER!<br>
100-499: Per Unit PRICE IS $4.25 <br>
500-999: Per Unit PRICE IS $3.25 <br>
1000-4999: Per Unit PRICE IS $1.25 <br> </font>

<P><P>

<B> GOT IT ? </B> <p><p>
