App Errors Preventing Deployment

I have recently created an app to track leads, to do this I used a sample app and edited it, keeping some parts of data and removing other parts.

The app is at a point where it shows no errors (red dots), however when I attempt to deploy the app I have a number of error (see attached images) which I can’t seem to get rid of.

Would anyone be able to assist me with this issue?

Thanks,
David.
