There is an odd glitch when switching membership types at renewal so that, though the contribution is successful, the membership renewal fails. In trying to address this manually, I get an error: "please enter a valid amount". There is no "amount" field on the edit page for the membership. I presume it is tied to the contribution somehow even though the contribution succeeded and the renewal failed. The minimum fee for "School Board - 30" is $1245 (the amount before HST), so I don't think that is it. It worked fine for another transaction going from 10 to 20. Very odd. Any thoughts?
