Marco Zinn	Friday 24 October 2003 11:58:23 am I need to do some calculations in a template (pagelayout.tpl), like this pseudo-code: level=$node.path.depth (not correct, but you get the point) span1=level+1 if span1>10 then span1=10 span2=10-span2 As you might imagine, this will be used for two column-spans in a table, which has 10 columns. I even have a problem with the first assignement. I tried {let level=$the_variable_name} but even that did not work. Is "level" a reserved word? For the other lines, I will need the "inc", "min" and "sub" operators (from http://ez.no/developer/ez_publish_3/documentation/development/libraries/ez_template/operators/arithmetics), but I don't know, how to use them for the calculations I need. Any code-hint (or working example code-snippet) is highly appreciated! TIA Marco http://www.hyperroad-design.com
Vivienne van Velzen	Monday 27 October 2003 12:57:39 am Hi Marco, I tried the following, and it worked for me. {let level=count($node.path_array) span1=min($level\|inc(), 10) span2=sub(10,$span1) } {$level}<br> {$span1}<br> {$span2} {/let} I didn't have any trouble using 'level' as variable name. Maybe it's a namespace issue? Hope this helps, Vivienne

Hi Marco,

I tried the following, and it worked for me.

{let level=count($node.path_array)
     span1=min($level|inc(), 10)
     span2=sub(10,$span1)
}
{$level}<br>
{$span1}<br>
{$span2}
{/let}

I didn't have any trouble using 'level' as variable name. Maybe it's a namespace issue? Hope this helps,

Vivienne
