01 Toyota Sienna will not shift

Hello,
I was curious to see if anyone can help.
My Sienna will not shift into gear at all. A few weeks ago I noticed it was getting harder and harder to get into drive and back into park. I thought maybe something spilled over the stearing wheel, so I cleaned it out and still had problems. Now, as of Friday it will not shift at all. I can't even budge it out of park.

Any help would be much appreciated.

Thanks in advance,
Will
