This may be a question for the developer of the Authorize.net plugin but when using this plugin, setup for a specific form, I select trial period by checking the enable box and only the trial amount appears. Opposed to doing the same with Paypal and a trial amount and trial period drop down appears.
When checking the source code of the page, I can see that the trial period select box is commented out "<!-- -->". I am hesitant to edit the plugin as I presume this was commented out for a reason.
I have tested a transaction to see if it defaulted to one month however the payment start date appears as the same date the form was submitted, highlighting the fact that it seems to be ignoring any trial period.
Can anyone provide an advice or assistance as to how I can get this to work.
Thanks!
