Mouth stays open

So Ive been reading this is a common problem with importing characters, Ive read and tried a few of the work arounds but havent had much success. Im new to all of this and am enjoying learning it all, but Im having an issue with when in play mode the characters mouth is open. I am using FemaleMovementAnimsetPro through Playmaker and have used CC3 to make my character and import her in. I just purchased Salsa LipSync and have had success getting the lips to move and speak BUT the mouth stays open the entire time. Has anyone else done roughly the same thing and have a solution? Thanks

I have found my solution.

Using this script and setting blend shape index to 0 and the Min range at -180 seems to have corrected my issue.
