[oopic] Serial To LCD messing up

I am passing a string of numbers to an ooPIC-R through a serial port
and having it display the numbers on a serial LCD. The first time it
gets the string it displays the number correctly. But the second time
it will first show the first string number it received from before and
then show the second string number it received now. Here is my code:
The string of numbers I send from the PC is in the format #xx , e.g.
#12 or #48.
Thank you so much for your help!

LCD As oLCDSE
Serial As oSerialH
X As oByte
Y As oByte
total As Byte
X=0
Y=0
total=0

LCD.IOLine = 16
LCD.Baud = cv9600
LCD.Clear
Serial.Operate = cvOn
Serial.Baud = cv9600

Start:
If Serial.Received = cvTrue And Serial.Value = 35 Then
LCD.VString = "got #"
Goto FirstDigit
EndIf
Goto Start

FirstDigit:
If Serial.Received =cvTrue Then
X= Serial.Value
X = X - 48
LCD.Clear
LCD.VString = "got 1st digit: "
LCD.VString = Str$(X)
Goto SecondDigit
EndIf
Goto FirstDigit

SecondDigit:
If Serial.Received = cvTrue Then
Y = Serial.Value
Y = Y - 48
LCD.VString = "got 2nd digit: "
LCD.VString = Str$(Y)
Goto ProcessTones
EndIf
Goto SecondDigit

ProcessTones:
LCD.Clear
total = (X*10 +Y)
LCD.VString = Str$(total)
Serial.VString = Str$(total)
Delay = 2000
LCD.Clear
LCD.VString = " Ready "

Goto Start
