Cant update quantity (BillingInterval) The import file is missing a required column.

[socalstyle]

I get the following error when trying to update my product quantities.

Column: (BillingInterval) The import file is missing a required column.

Can someone please tell me why this is happening? I manage my items through attributes, I dont put any pricing information on the master main level sku, and I sure as hell don't need the billing interval field to begin with. But to import initially I had to leave these columns in the attribute file for some reason

Unit Weight Length Height Width ContainerCode BillingInterval SubscriptionPeriod IntervalBegin NewBillType StartupFee RenewUpdateInd
0 0 0 0 self 0 0 P F $0.00 No
0 0 0 0 self 0 0 P F $0.00 No

So I am wondering if this has something to do with it?
