Growing squash up a frame

Last year a lot of the squash got eaten by rodents. The best way to keep them down is to keep the area weeded and short so they don't have anywhere to hide. This is tricky with the squash plants rambling all over the place, so this year I decided to plant them to grow up a frame.
They will be planted at the side where the ground is higher so they grow forward towards the sun.

There is also a courgette planted next to them (out of shot) as this soil is nice and fertilised with chicken and rabbit poo.
