Mix and match then select quantities on product field

Also, When I have an offer of products how to I add mix and match offers. I can do 2 for 3 on the same item but not able to mix the same brand of product but different flavours. 

I can see that you already added a quantity box on each product:

This allows your users to select multiple quantities of each product then select another product.

Or if you're referring to something else, please let us know in detail so we can check. A screenshot might help. Here's a guide on How-to-Post-Screenshots-to-Our-Support-Forum.

Hi 

Yes the user can select multiple quantities but what is not happen is when I have an offer

e.g the step up meals are 3 for £10 but I want it so they can select mix and match. Say 1 of each step up meal. The offer only shows of they select 3 of the same variety 

Hope that makes sense 

I would suggest you to create one main product and add the variants as sub-products. 

If you want offer a product with multiple variants and you want your customers to be able to choose many of them. Instead of creating a separate product entry for each variant, JotForm can automatically create sub-products for you by specifying, which option to base them from.
