OI Input Autonomous

[Ultima]

I have a few questions. Well first of all I edited the code and this is what it looks like now as I try to compile:

void auton_select(void)
{
static char last_sw1;
static char last_sw2;

if(p1_sw_trig == 1 && p1_sw_trig != last_sw1)
{
if(auton_select < 2)
{
auton_select++;
}
else
{
auton_select=99;
}
}
if(p1_sw_top == 1 && p1_sw_top != last_sw2 && auton_select > 0)
{
if (auton_select == 94)
{
auton_select= 2 ;
}
else
{
auton_select--;
}
}
last_sw1 = p1_sw_trig; //oneshot the trigger and top buttons
last_sw2 = p1_sw_top;

User_Mode_Byte = auton_select;
}

Second of all, how would I got about declaring auton_select as a global variable, and third I would need to get around the following errors:

C:\2007 arm code\FrcCode2005v2.4\user_routines.c:661:Error [1128] compatible scalar operands required for comparison

The code is from 2005 since we are just testing our prototype arm with the 2005 controller.
