Billing

We've successfully setup the site now and did the test registration. My 'employer' sent me the following message.
One thing I noticed, though, is that when someone joins, the payment goes through - however, it is set currently to bill for their first month the day AFTER they join.
This is the code
[s2Member-Pro-PayPal-Form level="1" ccaps="" desc="$9.95 USD / Monthly ( recurring charge, for ongoing access )" ps="paypal" cc="USD" ns="1" custom="nacvas.org" ta="0" tp="0" tt="D" ra="9.95" rp="1" rt="M" rr="1" accept="paypal,visa,mastercard,amex,discover,maestro,solo" accept_via_paypal="paypal" coupon="" accept_coupons="0" default_country_code="" captcha="0" /]
How do I fix this?
