Good morning, Rosemary. It looks like the pivot bar has actually ripped out a piece of the bottom of the sash. This will make things a little difficult. I believe it was caused by tilting the sash in without opening it a few inches. Usually, the window company puts a decal on the sash on tilting procedures. By tilting it without raising it a little bit, you cause twisting pressure on the tilt bar and the bottom of the sash broke off. You may want to contact a local repair man who can patch that up.
