[RESOLVED] Referencing another project

[HardyRexion]

I'm trying to add a contacts project to an existing project. I'm just practicing as I've never done it before, but I'm obviously doing something completely wrong

As you can see from the attached image, I cant seem to reference frmManageContacts from the Contacts project and can only reference frmManageContactTypes

I know I'm going to feel dumb, but what am I doing wrong?
