checking mozilla version 1.0 and windows on install

[Jason LaBumbard]

I want to check to make sure that my xpi is installed on mozilla 1.0 and
a windows system.  Is this the correct way to do it?

First check windows...

    if ('platform' in Install) {
      platformStr = new String( Install.platform );

      if (!platformStr.search(/^Win/))
        platformNode = 'win';
      else
        cancelInstall(err);

    }
    else {
      var fOSWin  = getFolder( "Win System" );

      logComment( "fOSWin: "  + fOSWin );

      if (fOSWin != null)
        platformNode = 'win';
      else
        cancelInstall(err);

    }
    if (platformNode == 'win') {
      logComment("Installation started for Win32 platform");
      addFile(COMNT_3, G_SPLASH_FILE, G_PROGRAM_DIR, "");
      registerChrome(CONTENT | DELAYED_CHROME, getFolder(G_CHROME,
G_JAR_FILE), G_CONTENT);
    }
    else
       cancelInstall(err);

Then check if mozilla version 1.0 (buildID is 20020530)...

if(!typeof buildID == "undefined")
{
      if(buildID != "20020530)
          cancelInstall(err);
}


I think the windows part works ( it recognizes that I am using windows 
but I dont have any other OS to test it on to see if it fails).

It gives me errors when I try to check the mozilla part.
The error is...
    ** Line: 87 unterminated string literal

      Install **FAILED** with error -229  --  09/30/2002 15:51:27

Line 87 is this line -> if(!typeof buildID == "undefined")
I have tried if(typeof buildID != "undefined") and getting rid of that 
and just checking if(buildID != "20020530") as well but it gives me the 
same error!!

Can anyone see what I am doing wrong?

Thanks!
