Populate text boxes dependant on the display in 2 comboboxes

Thank you in advance for any help I can get that retains the hair on my head. I am currently developing a spreadsheet package for a small catering business. I have tried to write the VBA code to allow me to call up the supplier in combobox1, which will then populate the product list with specific items in combobox2. I then need to display textboxes with the product information such as cost, storage, pack sizes etc on a user form.
