Problem

I have a website with a payment form, I want to add recurring payments. how would i do that? what `ID`'s do I need to use in the form fields? I saw a `WordPress` `plugin` that uses `a3` `t3` and `p3` like so: ``` <input type="hidden" name="a3" id="a3" value="" /> <p class="donate_recur"><label for="recur">Repeat Donation</label> <select name="t3" id="t3"> <option value="0"> Do not repeat </option> <option value="D"> Daily </option> <option value="W"> Weekly </option> <option value="M"> Monthly </option> <option value="Y"> Yearly </option> </select> x <input name="p3" id="p3" value="'.$dplus['duration'].'" type="text" style="width:10px;" /> ``` I'm not sure what `a3` is but `t3` is ever how long the transaction will happen, and `p3` is how many times it will happen. I looked a little on the web and i found how to make a `PayPal` button for some kind of product with recurring payments. but I need it to be dynamically inputted. thank you.
