google checkout problem

I have installed the google checkout module. It works perfectly if the pricing for a subscription is set to "Always same period and same price"

However, I need a trial period. When I change the setting to "different first period and price for registration and upgrade", I get this message after entering registration details

Warning: Trying to subscribe 2 days to Google Checkout, subscription augmented to 1 day. in ....../components/com_comprofiler/plugin/user/plug_cbpaidsubscriptions/processors/googlecheckout/cbpaidsubscriptions.googlecheckout.php on line 557


Any ideas on how to fix this? Thanks!

Google Checkout doesn't allow 2 day durations. You need to use durations within Googles limitations. Limitations as follows.

1 Year,
1 Month,
2 Months (Every Two Months),
3 Months (Quarterly),
12 Months (1 Year),
1 Week,
1 Day,
7 Days (1 Week),
15 Days (Semi Monthly),
30 Days (1 Month),
90 Days (Quarterly),
365 Days (1 Year)

Any durations outside the above ranges are forced to the closest allowed duration.
