Renders invalid HTML

In counter.module I replaced:

line 258:
$output .= '<li/>'.t('Site Counter: '). ($counter_initial_counter+$counter_total);
with:
$output .= '<li>'.t('Site Counter: '). ($counter_initial_counter+$counter_total). '</li>';

line 266:
$output .= '<li/>'.t('Unique Visitor: '). ($counter_initial_unique_visitor+$counter_unique);
with:
$output .= '<li>'.t('Unique Visitor: '). ($counter_initial_unique_visitor+$counter_unique). '</li>';

line 274:
$output .= '<li/>'.t('Registered Users: '). ($total);
with:
$output .= '<li>'.t('Registered Users: '). ($total). '</li>';

line 282:
$output .= '<li/>'.t('Unregistered Users: '). ($total);
with:
$output .= '<li>'.t('Unregistered Users: '). ($total). '</li>';

line 290:
$output .= '<li/>'.t('Published Nodes: '). ($total);
with:
$output .= '<li>'.t('Published Nodes: '). ($total). '</li>';

line 298:
$output .= '<li/>'.t('Unpublished Nodes: '). ($total);
with:
$output .= '<li>'.t('Unpublished Nodes: '). ($total). '</li>';

line 302:
$output .= '<li/>'.t("Your IP: ").$counter_ip;
with:
$output .= '<li>'.t("Your IP: ").$counter_ip . '</li>';

line 312:
$output .= '<li/>'.t("Since: "). $counter_since;
with:
$output .= '<li>'.t("Since: "). $counter_since . '</li>';

line 314:
$output .= '<li/>'.t("Since: "). $counter_initial_since;
with:
$output .= '<li>'.t("Since: "). $counter_initial_since . '</li>';

Sorry, I can't make patch or diff files! :-(
Hope this helped!
