Media offline when opening saved fusion comp

I new to Davinci and have made my first fusion comp - an animated subscribe button following (I followed a YouTube tutorial.) I looked for instructions to use it in another project - I have tried saving the nodes as a setting file and opening in a new fusion comp also tried exporting the fusion comp but the media remains offline in the new project. I have tried the relink button and still I can’t seem to find what I am doing wrong. Grateful for any help.
