Help with flash

[1986]

i dont have the money to buy a external flash so i use the one built into the camra but now every time i try to use it it says "error 99"

i click the shutter button and it says "busy"
Then it does the "error 99"

I know that some times the errror 99 is like a lens thing

can anyone help me?

If you did not all error messages are listed in your manual.
