The UPDATE command above looks fine (besides the wrong quoting if the
Name value, but that probably is only a typo.).
To be sure, that your query actually looks like this, you might print
on the screen before the actual query.  Something like:
  $query = 'UPDATE ... WHERE CustID = 1102';
  print "Query: " . htmlspecialchars($query) . "<BR>\n";
  $resultid = mysql_query($query) or die("Syntax error in SQL query!");

How did you check the updated value?  The UPDATE command itself
doesn't return a result row, so you probably have done a SELECT and
then retrieved the result of this SELECT.
Maybe the error is somewhere there?
