HELLP!!! BUG in PayPal Button Generator

[Photoman]

Help!! This is a 2 part problem... I'm trying to set up a Lifetime subscription.

1) I'm using the latest s2member plugin for word press. When I create a button for a level 1 I get the following error back from PayPal: Invalid first trial period. You must specify valid values for the A1, P1, and T1 parameters for a subscription.

2) No mater which subscription option is chosen the folliwing CODE does NOT change:
<input type="hidden" name="src" value="1" />
<input type="hidden" name="sra" value="1" />
<input type="hidden" name="a1" value="0.00" />
<input type="hidden" name="p1" value="0" />
<input type="hidden" name="t1" value="D" />
<input type="hidden" name="a3" value="0.01" />
<input type="hidden" name="p3" value="1" />
<input type="hidden" name="t3" value="M" />

I've looked up the codes on Paypal for the values, but am not sure what I need to change to get it to work. (Ideally I should use the Buy Now, but I want to force the user to sign up; thus I need to use a 'subscription" level.

Thanks!
