Error code problem

[butterfly]

HI

I MAKE A INT:
int son=0x00;

and use in a funtion:
analogoku(int k)
{
int i=0;
int1 neg=0;
int1 sonuc=0X0000;
int16 sonuc1=0X0000;
ilk=0x00;
son=0x00;



set_adc_channel( k );
delay_us(20);
sonuc1 = Read_ADC();//

switch (k){
case 0 :
break;
case 1 :
////hesap AÇI

sonuc1=sonuc1-zerocrossangle;
if(sonuc1>0x8000)
{
sonuc=~sonuc;
neg=1;
}
sonuc=0x00;
while (sonuc1<=8000)
{
sonuc1=sonuc1-stepang;
sonuc++;
}
sonuc=MASK&&sonuc;
if (negoreg==0){
if (neg==1){
sonuc=sonuc || NEGATIF;//negoreg=0...negreg=1
}

}
else
{
if (neg==0){
sonuc=sonuc || NEGATIF;//nogoreg=1..negreg=0
}
}
sonuc=sonuc || ANGLE;
ilk=make8(sonuc,0);;
son=make8(sonuc,1);////////gives error
putc(son);
delay_us(20);
putc(ilk);

break;
case 2 :
sonuc1=sonuc1-zerocrossdistance;
sonuc=0x00;
while (sonuc1<=8000)
{
sonuc1=sonuc1-stepdis;
sonuc++;
}
ilk=make8(sonuc,0);
son=make8(sonuc,1);////////gives error
putc(son);
delay_us(20);
putc(ilk);


}
}

both gives error:
Invalid parameters to built in function

why is that??

Of course it does.
'Sonuc' as you have declared it, is a _single bit_. The 'make8' function, allows you to take one byte of a multi byte value. You can't use a function expectingf a value larger than a byte, with a variable that is smaller than a byte...
