1999 Chrysler Sebring Gears won't change in car

I was driving on my way home last night and my speedometer stopped working and my car would not change into gears from drive.I can use reverse in the car. It drives but it just won't change out of low gear. I don't want to keep driving it and burn something up so could someone please give me an insight on what this could possibly be. It's the only mode of transportation I have so I need to get it fixed. Any info would be helpful. Thanks in advance.
