How to pass in two arguments to a props function in styled components

Question

I have a styled-components in my React component and it currently uses the props feature on styled components.

I need to style using another property but I keep getting an error when I try to pass it in.

This is what I currently have and this works fine.

border: 1px solid ${(props) => (props.isError ? "red" : "transparent")};

This is what I am trying to achieve:

border: 1px solid ${(props) => props.isError ? theme.Colors.red : "transparent"};

Is there a way to pass in the theme as an additional prop in the props function?

I keep getting this error **Cannot find name 'theme'.**, even though it is being used in other parts of my styled component.
