#FUSES , AN4 and LVDIN ( PIC18F6720 )

[Kada]

How can I define AN4 as an analog input?

...............
setup_adc_ports(ALL_ANALOG|VSS_VDD);
setup_adc(ADC_CLOCK_DIV_64);
setup_vref(FALSE);
.......

but still have problems with channel 4, it seems that it is not an analog input.

#OPT 5 // optimization level 0-9
#device ICD=TRUE
#device ADC=10
#use delay(clock=9830400,RESTART_WDT)
#fuses H4 // Crystal osc(2,457600MHz) * 4
#fuses NOOSCSEN // Oscillator switching is disabled
#fuses PUT // Power Up Timer, ca. 72 mS.
#fuses BROWNOUT // Reset when brownout detected
#fuses BORV25 // Brownout reset at 2.5V
#fuses WRT // Writting to flash from a program
#fuses NOLVP // No low voltage prgming, B3 used for I/O
#fuses WDT128 // Watch Dog Timer uses 1:128 Postscale
#fuses NOWRTC // No writing to the configuration registers
#fuses NOPROTECT // Code not protected from reading
#fuses NOEBTR // Memory not protected from table reads
#fuses NOCPD // No EE protection
#fuses NODEBUG // No Debug mode for ICD
#fuses STVREN // Stack full/underflow will cause reset
#fuses CCP2C1 // CCP2 input/output multiplexed with RC1
#fuses NOCPB // No Boot Block code protection
#fuses NOWRTD // Data EEPROM not write protected
#fuses NOWRTB // Boot block not write protected

Note that AN4 is NOT pin A4 but pin A5 on the micro.
