Thanks for the direction, Jason. It shortened up the learning curve on how the PS options work out.
"SELECT DISTINCT o.OptionName FROM ps4_options AS o, ps4_products AS p, ps4_productoptions AS po, ps4_optiongroups AS og WHERE og.OptionGroupName = 'Size' AND og.OptionGroupID = o.OptionGroupID AND po.OptionID = o.OptionID AND p.ProductID = po.ProductID AND p.ProductGroup = %s ORDER BY o.OptionName",
