Howto set max loop on month name to 1 in a calendar listing events

Monday 19 April 2004 8:15:43 am

I have a calendar which prints out events on a page of class id 8.
The events comes with date, title and description, like this:

"Date: 2004, 03.05", Title: Mac design, Description: bla bla bla..

I want to make the page look like this with sorting by months:

Mars
"Date: 2004, 03.05", Title: Mac design, Description: bla bla bla..

May
"Date: 2004, 05.05", Title: eZ design, Description: bla bla bla..

BUT the question is when I add case match for 01 which is January in the line_class_8.tpl I get a loop for the monthname..I only want the name of the month to print only once.
Tried to set a variable in the template to check when the monthname is printed once, but won't help :(

I have a pagelayout with:

{section name=Child loop=sort($child_list)}

<tr>
    <td valign="top">
        {node_view_gui view=line content_node=$Center:Child:item}
    </td>
</tr>{/section}

Child:item uses line_class_8.tpl for viewing..with the code:

{switch match=$node.object.data_map.from_date.content.timestamp|datetime(custom,"
%m")}
{case match="01"}
{section show=ne($val,2)}
{let val=2}
{section show=eq($val,2)}
January
{/section}{/let}{/section}{/case}

I tried to make something with the section..val etc., but it's printing out January for every events..I only want January to appear only once.

I wanna know how is it possible to write this in the ez template:

{if not eq($bol,1)
let bol=1}
{section show=eq($bol,1)}
January{/section}
