Good but Im stuck on Jurassic park III

Its been great up until I got to Jurassic park III, it wouldnt let me go to the next level. I played the first three parts of it over and over and I cant get across this trench to access the next sequence of levels. I dont know why this is happening and its very frustrating. If anyone could help that would be great.
