Webflow Issues: Unknown Variable Error and Portfolio 22 Component Failure

Ahh, I'm having a decent amount of issues. They are listed below along with my read only link

1.
When setting the color of elements (namely typography), I am getting the message: "Error: Unknown variable". I tried doing what I thought it meant by resetting "the style property associated with this reference", but what I tried did not work.
2.
I cannot get component "Portfolio 22" to work. When I hover over the different sections, the image does not change.
