Why isn't my tolet filling up with water?

What part, the tank in the back, the bowl, both ?

Is the water turned on to the toilet?

The back isn't filling up. And yes the water is on. That's what is so strange:(

Thank

Which ballcock do you have? Let me know, Tom

The first one

Turn the water off. Lift the float arm up and rotate the cap counter clockwise a little bit and the cap will lift off. You will then see a black circular seal. Lift the seal off. Put a cup over the fill valve and turn the water back on. Have water? If so, flush well, turn the water off and put the cap back on, lifting the arm and turning clockwise. Turn the water back on and you should be good to go. If you have no water coming out of the fill valve, you have a blocked angle stop or another blockage and will need to trace that back.

Thank you I will check it out when I get off. Thanks

It didn't work:( No water. So do I have to call a plumber now? Thanks

Are you sure the shutoff under the toilet is on? Sometimes the handles corrode and spin but do not turn the water on. If you are sure you have water on, turn the angle stop off. Remove the hose from the ballcock, put a towel over it and carefully open the angle stop. Water?
