Interrupt:syntax error

[hokelvin66]

i was making 4 digit 7 segment multiplexer using PIC18F2550 using C18-compiler.However i had faced a problem that my "void interrupt isr (void)" encounter "c:45:error:syntax error" and the other code was fine.What is the problem?

Do check the C18 C compiler User's Manual. In PIC18F, there is high and low priority interrupt, so should be two interrupt functions.
