BCE0044: expecting error

got a few errors and I'm confused on how to fix them, any help will be much appreciated.

 function playerstatecontoller() 
 {
     If ((Input.GetAxis("Vertical") !=0 || Input.GetAxis("horizontal") !=0))
     {
         If (Input.Getbutton("Sprint"))
         {
         playerstate == 2;
         }
 //Line below it says that it was expecting }, found 'else'
         else
         {
 //Line below expecting :, found ';'
         playerstate == 1;
         }
     else
     {
     playerstate == 0;
     }
 }
 }
