I followed a recipe and did it by the letter, the ingredients, the temperature, the rennet, everything and it came out crumbly. I don't understand why.
Did you knead and pull the curds, reheating them as necessary?
This is the recipe I usedFrom my limited knowledge its that kneading and pulling stage which turns curds to stringy mozzarella.
Do you have a link to the recipe you used Puggles?
Yes, as I pulled it it became less a handful of pieces and more like a smooth pice of cheese.Never done the practice but I've seen the movies.
It's what medtran49 and Morning Glory are saying: the kneading and pulling is critical.

Doesn't matter if you don't speak Italian - you can see how this guy makes it in Reggio Calabria.
