Q1: Why can’t I click the button Contact Supplier?
A1: If you fail to click the button Contact Supplier to add the product to ask for quote and it feeds you back with flashback, there must be products in the quote basket of another supplier. Mass sending inquiries with multi suppliers and products is prohibit, so you just need to empty the products in the quote basket by clicking the red X in the request quote page, then you can click the Contact Supplier button and send the inquiry.
