10 day free trial using Authorize.net Pro For

I am trying to offer a 10 day free trial using an Authorize.net Pro Form shortcode. When creating the shortcode, I get a popup message saying that the maximum trial days is 7, and that I should use weeks or months. I don’t want two weeks, though – I want 10 days. I noticed in the Changelog that last May you fixed this for Paypal (quoted from the Changelog: “(s2Member Pro) PayPal® Pro Forms. This release removes all limitations on the maximum length of an initial trial/period. It is now possible to offer any number of days/weeks/months/years for free, or at a different initial rate.”).

Has the restriction also been removed for Authorize.net? I don’t want to assume it has been fixed and then find out in 10 days that my customers are not being charged or something.

This is the shortcode I would like to use:

[s2Member-Pro-AuthNet-Form level=”1″ ccaps=”” desc=”10 Days @ $0 / then $28 USD / Quarterly ( recurring charge, for ongoing access )” cc=”USD” custom=”chiccritiqueforum.com” ta=”0″ tp=”10″ tt=”D” ra=”28″ rp=”3″ rt=”M” rr=”1″ rrt=”” accept=”visa,mastercard,amex,discover” coupon=”” accept_coupons=”0″ default_country_code=”US” captcha=”0″ /]

Will it work?

Thanks!
