Best way to display selected resources

I am in search of advice on the best way to handle this functionality: 

Early on in a project (Captivate 9) I have a slide where I want individuals to select specific categories. (They can select more than one).  I then want that to inform which resource links show on a later slide.  So for example, they choose "English Langauge Learners" on slide 3 and then when they get to slide 13 resources related to that demographic show up.

I think the best way to do this will be to have their actions on slide 3 assign values to a variable and then have the resources be tied to the value of that variable, my question is what is the best way to get the variables assigned on the early slide?  I'd like people to be able to select something, see that it is selected, but also be able to unselect it if they selected it in error.

Or if there is an alternative/better way to make this functionality happen that you know of please advise.
