I'm making a simple text adventure and was wondering how to sake the data from each choice to affect the choices later.

One approach you could try is to make some additional data table elements, one being a datatablerowhandle of maybe a required text prompts and the others bring maybe required past choices choices for that prompt. Without knowing your system it’s hard to say exactly how to set this up, but I hope this will help. And like everynone mentioned you’ll probably want to implement a variable or two in your saved game to track choices
