why does the spray bottle quit spraying ??? HELLLLP?

Assuming you mean a push pump of some variety, it's either empty of fluid or airlocked because you tilted it in a manner that took the pickup tube out of the fluid.

All you need do is ensure the pickup tube is immersed in the fluid, then pump repeatedly until it again sprays. After that, use it only in a manner that ensures the pickup tube is never out of the fluid.

If that fails to get it going, contact the manufacturer of the product, and complain about the packaging.

Within the spraying mechanism is a sophisticated component called the squirter, its the part that squirts stuff. When the fluid travels through the squirter it is compressed up and out through the nozzle. Debris and impurities get trapped in here. Best decision is to buy parts and replace the squirter since parts are cheap, ask around and automotive store since squirters are used as fuel injectors as well and parts can be substituted with some lotta know-how.
