I apologize for the double post, but I also forgot to mention that the conditions for the WHERE clause are also coming in as an array. So, I'll need to construct my WHERE clause with an unknown number of elements. This part I've completed. It is just the storing of the data in the array and the proper loop I am having trouble with.
