unable to add widgets to sidebar

I have registered my sidebar with the code below.

<?php
## registar sidebars
if ( function_exists('register_sidebar') )
register_sidebar(array(
  'name' => 'Col 1 Top',
  'id' => 'col1-top',
  'description' => '1st column top widget',
));
?>

I call to it from:

<?php if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar('col1-top') ) : ?>

When I go to the dashboard and try to add a widget to the page it will not save. Image here

[No bumping, thank you. If it’s that urgent, consider hiring someone.]
