I still have no idea what exactly you are trying to do. I did notice you have no relationships established.



I recommend you build a model (tables and relationships) representing the "business" you are working with. It will make your coding and retrieval much more straightforward.

I see Customer, Quotes and Products. On that basis I suggest you look at this data model and see if it helps with your database.

Good luck with your project
