Sketch will not close

Hello! I am trying to make a few cuts in solid works, but I keep receiving an error massage that says that my sketches are not closed. I have tried to close the sketch using relations and still no luck. How do I close the sketch? I have also tried to go to tools>sketch tools>close sketch to model, and I received an error saying that the sketch could not be closed. Any suggestions or possible solutions would be helpful.
