Why cant I draw a track between these two pads?

Im probably being an idiot but why wont it let me draw a track between these two pads? it keeps stopping short

They must have different nets and KiCad protects you against making error connection.
We see the net of the pad you want to connect to, but not see what is the net of pad you started from.

ahh yes. thats the problem. thankyou so much
