Remembering choice

Hello fellow Twiners.

Am pretty new to this and am having some issues with choices made in 1 passage that's should link to another passage. The difference in choices affects the story.

For example, in passage 5 "David wants to buy a gift for his wife. Choice A a bag, choice B shoes"

Now in passage 10 " David gives his wife the gift. If he bought the bag (choice A) he gets kisses, and if he bought shoes (choice he gets hugs.

Now i can't seem to figure the codes out.

Any help would be highly appreciated
