Hi cpitts,
I wanted to give you an update on the error message that you were experiencing. The screen that you were looking at is part of Method CRM Full Blown which we unfortunately don't support anymore and won't update. The QuickBooks_SalesOrder from TemplateOnlineCRMQBDesktop (#380) screen that I had mentioned above is part of the new Method CRM and Method CRM Pro that we have available.
The error message that you had experienced was actually happening on the screen called SalesOrder_CreateInvoice which is also part of the Method CRM Full Blown Edition.
My best advice is for you to either fix the screen yourself by either making a copy of it, finding the action that has the Start Loop Through Grid action that is missing the End Loop Through Grid action or update to the new Method CRMs that we currently have available.
I hope that this helps.
Ronen
