Reading text from a file , evaluting it and updating table

I am stuck on a step in below script. It is reading from a text file , picking up a value, evaluating it and based ont the value returned , updating oracle table ( using SQLplus ) with one of the value returned.

All thing apart from BODY of IF and ELSE is working. So issues are either with connection or with datapassing

Please help me

dim fs, txt, line, yesno , cust_id
set fs = CreateObject("Scripting.FileSystemObject")
set txt = fs.OpenTextFile("E:\batchfiletest\Eapp3\scotia1.txt", 1, false) 

' loop through all the lines
do while not txt.AtEndOfStream
    line = txt.readLine

' read the character and store it in a variable
    yesno = Mid(line, 127, 1)
    cust_id = Mid(line, 1,20)   

' execute the correct query
    if yesno = "Y" then

    set WshShell = CreateObject("WScript.Shell")
    set oEnv=WshShell.Environment("Process") 
    cmdString = "E:\oracle\product\10.2.0\db_1\BIN\sqlplusw.exe -S sysman/csaadmin@convcsd

    UPDATE csa_sli_all.T_CONV_quote set HOLD_CODE = 'CAQ' where quote_id =  cust_id ;"

     ELSE  
    set WshShell = CreateObject("WScript.Shell")
    set oEnv=WshShell.Environment("Process") 
    cmdString = "E:\oracle\product\10.2.0\db_1\BIN\sqlplusw.exe -S sysman/csaadmin@convcsd

    UPDATE csa_sli_all.T_CONV_quote set HOLD_CODE = 'PVQ' where quote_id =  cust_id ;"

    end if
loop
