Need help with 4-legged walk cycle

hello everyone, first post

im making a animation with a (4-legged) beaver as a character and i need help with the walk cycle

so far, ive only animated the front-two legs but one of them doesn;t look right to me and i can’t find out what is wrong

both my fla and swf are attached in the zip file if you want, there is also a swf only if you don’t wanna download the fla file

im using the animation at: http://www.toonboom.com/qtFlash/workOut5_final.html
as a guide

any help would be greatly appreciated
