If you wait a week, then i think you will wait for another week.

As Pappenheimer says. Try it with a smaller code. Save the script you have, then make a new one. Start by simple animating with walk and idle. Then try to blend the two togehter. Then add another animation and another blend.

I just fly over your code, but i havent time to look deeper in that.

Try it out. Sometimes you wil find the answer and you say: Oh my god. Thats so easy. (Zu Deutsch. Irgendwann fallen dir die Tomaten von den Augen und du sagst: Verdammt warum bin ich nicht gleicht darauf gekommen).

And by the way:
If you spambumping your post, no one will help you.
