"daily pass" values

Hi guys, thanks for your terrific plugin. I’m having a bit of trouble with the “day pass” functionality, though.

My website features a photo workshop in 22 video lessons; the first is free, the others for a nominal fee.

I love the “day pass” option your plugin offers, but it seems I’m not configuring it properly. What I had in mind for it was actually an “all access” pass to the workshop, good for 180 days, but when I configure those values I get an error message at the paypal end.

For now I just de-activated that function, but I’d appreciate help getting it dialed in…
