Electrical Wiring in the Home/bathroom gfic replacing outlet


replaced outlet with a gfic receptacle this box also has a switch for overhead light everything was working fine before the switch and receptable was replaced gfic works but when you use the switch it trips the gfic  I know the wiring is wrong some place but I hope you can help me

There is probably a ground fault with the light.  Either the light is connected to the ground, or the neutral is connected to another circuit.  However, the light is not required to be on the GFCI circuit.  So the wire for the light should not be connected to the load side of the GFCI.

If the GFCI was connected where only the switch was connected, and there is only two wires coming from one cable, you can't connect an outlet there.

If this doesn't help, ask a follow up question and give me more details what was there, and what you added, and what is on the circuit.
