Livecode Server and Repeat Scripts on Server

Ok, FWIW, this appears to work:

<?lc
put $_POST["username"] into tUsername
put $_POST["password"] into tPassword
put $_POST["email"] into tEmail
put url("file:users.txt") into tUserFile

repeat for number of lines in tUserFile
if item 1 of line 1 of tUserFile is tUsername then 
put "Sorry, username (" && tUserName && ") has already been used. Try another."
exit repeat
else
delete line 1 of tUserFile
end if
end repeat

if the number of lines of tUserFile <1 then
--put url(“file:users.txt") into tUserFile
put return & tUsername & "," & tPassword & "," & tEmail & "," & "Button 1" --after tUserFile
end if

--open file  "users.txt" for write
--write tUserFile to file "users.txt"
--close file "users.txt"
--put tUsername & "," & "Button 1"
--end AddNewPlayer

?>

Thanks for the prodding Peter :)
