Need help with Attributes and variations

Hello, Im tryin to put the finishing touches to my site but can’t for the life of me configure my variations for my drop down menus.

Here is my site,

kirchcomp.com

I have a “Maker” attribute and a “Model” attribute. I want my drop downs to work like this, select a Maker first and then in the next box would be the model but only models that are associated with the maker. For example if you look at my site, if you were to click on the KC Mod 1 and the first drop down is maker. If you say select Glock there and then move onto the next drop down menu which is model only the G## models should be avalible for selection.

I know my variations arnt “all linked”. I have even deleted all the variations and redid them. I have been trying tons of different things and wasting a lot of time and just cant get it to work.

I hope someone can help, thanks!
