Can't push pull a window panel

Hello I have created a window and have used push pull to create the window panels but one of them won’t work. I have tried deleting the lines and trying again but it just won’t work. Also tried doing it from the other side and it won’t work.
It isn’t made in to a component yet.
The other panels worked fine? Any tips? Thanks.

Likely there is something in the way that prevents pushpull. Share the model here and folks will take a look.

Thanks. I realised the box wasn’t fully drawn which was stopping it.
