Hi there could be a number of reasons

 

1 Is your fmc set up correctly for the correct flight plan etc

2 Auto pilot wont engage below 400 feet and aircraft has to be trimmed etc

3 have you done the tutorials 1 and 2 yet good information is given in these

4 If the above doesnt help than do the search option gives you lots of answers for " autopitot"
