Tips for Incorporating Relume into Older Projects in Webflow

Hi! I am trying to incorporate Relume into an older project. I have copied a stule guide and all the classes seemed to sync nicely! My problem is with the variables. Some of the components are referencing variables that don´t exist in this project and webflow won´t allow me to change the variable without resetting the variable. Bet as I said, the variable don´t exist in this project so I can´t reset it. Does anyone have any tips or workarounds? A step by step guide to incorporating Relume in an older project would also be appreciated! Thanks!
