Select Bestseller only from two category

[pkdsgn]

Hi, I'm using LabTheme theme. On home page we using bestseller tab from LabTheme. I'm trying change SQL instance by adding "WHERE category id equal 3 and 14".  Becasue we selling cheap products too (as extra) it's they who occupy the first position in besteller, but I need show there only standard products. Can you help me find a solutions ? 

On standard bestseller module I'm using products by category showing actually product and It's work fine, but with module from LabTheme I have some problem.  

 

		$sql = 'SELECT p.*, product_shop.*, stock.out_of_stock, IFNULL(stock.quantity, 0) as quantity,

Check out the Advanced Bestsellers Module, it overrides the SQL so the bestsellers displayed by the shop are changed according to your settings. Should work with any theme that is using the getBestSales and getBestSalesLight functions.
