I never use waterfalls and never recommend them because they are very hard to keep germ-free and clean. Do you have a substrate?
You didn't say what the temperatures are in the basking area and in the rest of the cage. You didn't say what species of chameleon it is or what age it is.
The reason I asked if you were sure it was male is that females can often lay eggs even when unmated so its important to provide a suitable egglaying site.
You said...one of the lights is "a big daylight bulb (one of those ones that is supposed to make plants grow and everything). He dose not get direct light but this bulb was supposed to be the same as daylight"....any bulbs that I know of that are sold to be the same as daylight or to grow plants don't have the UVB range that the chameleons need so unless you are giving him a supplement that contains D3 he could develop metabolic bone disease.
You said..."I tried putting both crickets and worms directly in his mouth and he spit them out"...I asked you to do that because a chameleon usually will chew it down unless there is something wrong...but its not a sure test because there are other things that might make him not eat it.
You said..."I don't gutload his food, what is that? should I be doing that? I have just been feeding him crickets and kingworms from the petstore"...you should be gutloading the insects because the insects that come from the stores are not always fed properly and they should have their nutrition improved before they are fed to the chameleon and healthier insects make for a healthier chameleon. Here's a gutload that many people recommend...

I live in a northern climate and my chameleons don't get regular sunlight, so I have a UVB light on their cages and in addition to gutloading the insects I dust them with vitamins/minerals, calcium and a calcium/D3 powder before giving them to the chameleons. I dust lightly with vitamin/mineral powder once or twice a month, calcium/D3 once or twice a month and a couple of times a week with calcium.
Here are some articles that explain about vitamin D3, calcium and the part that vitamin A plays in the balance the chameleons need...

Here are some other sites that have lots of good information about chameleons too...

Chameleons are not one of the easy lizards to keep in captivity....but with proper care they can do well.
