There is a problem with the code, possibly the animator as well... Please help?

I think the problem may be with the animator but I couldn't be overly sure as I am a beginner. but just in case I have included the code in the space below. The problem is that my character will not switch animations at the correct time, if more screen shots are needed then please specify what parts of the program you need
