When I flush my toilet it is not refilling with water, and the water to the toilet is on what should I do at home before having to call a plumber?

See this link:

It is likely that your flush valve (http://www.fluidmaster.com/fill_products_main.html) (the tall thing standing up) needs adjusted, or it has just failed.

The 400A valve we use is about $5 and can be replaced in 15 minutes even if you've never done it before.

Yeah you are right I need to replace the flush valve but my daughter had turn the water off at the wall and that's the real reason it never filled with water thanks.

Glad you found the problem! http://www.jackson8.com/images/amhd/thumb.gif
