like on the picture, its 2 pics

i tried this thing but it do not work
loop:
lcdout $fe , $c0 , "Waiting.." , DEC3 try1 , "," , DEC3 try2
try1 = try1 + 1 : temp = 0 : tempf = 0
serin portB.2 , t2400 , [ temp1 , temp2 , temp3 , temp4 ]
if temp1 > temp2 then
Portb.4 =1 ------------putting a led here, maybe lcdout is confusing with serin
pause 500
portb.4=0
else
Portb.3 =1 -----------putting a led here
pause 500
portb.3=0
endif

goto loop
End
