Hi,

I am having some problems I am not the greatest with this type of things I am trying to do. I am looking for an answer and a easy way to learn to do this.

First off I want my customer to be able to change the quantity then when they pick the quantity the price will change automatically. I know there is a paypal way to do this but I want it to be done on my site. I am selling site credits kind of like zynga cash on the facebook games.

Kind of like

<select name="howmany">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
</select>

They will choose one of them options but there are three options to purchase and they are $5 $10 and $15

Now let's say if they choose 5 as the quantity and the $10 option then it updates to $50 and what ever the credit amount updates as well to 5 times the original. If you need more info just ask me.
