cannot connect electrical box wires in basement

I have all 4 wires and have tried over and over to connect but still get the message "I need something" every time. Tried different angles, carefully selecting the right spot, etc. Will not accept the wire from my inventory onto the connector. Please help.

Ignore my question - I must be stupid today. I thought I had picked up all the wires but missed one when I clicked on it. Assumed I had it but rechecked again and no. All ok now.
