Thanks Bob; sorry to take so long to get back on this. Other business has kept me away from it.
The 'NO AD' and 'WITH AD' strings we want to incorporate; it communicates to the buyer that lower qties do not have their ad imprinted on the calendars and higher qties do include their ad. Evidently when we import the string with 'NO AD' & 'WITH AD' portions (without any price), the system will default with price of $0.00 (see first image in my first post).
And it may make no difference at all, but here's a screenshot of the field within Miva Merchant that we input pricing for the TY16 (first item at top of thread that I intro'd with):
Everything else seems pretty straightforward although I don't know anything about arrays...I guess it's just ordering/sorting information.
