drupal - t() not printing a translated string -

i currenty try make module translateable using t() hard-codes-strings. since call t() advised in documentation don't have clue might doing wrong. call in block_theme of module.

hook_theme();

don't if important…

/* # themes {{{*/ function catchy_overview_theme() {   return array(     'catchy_overview_block' => array(       'template' => 'catchy_overview_block',       'arguments' => array('nodes' => null, 'terms' => null, 'imagecache_preset' => imagecache_preset(variable_get("catchy_overview_imagecache_preset", null)))     )   ); }/*}}}*/ 

catchy_overview_block.tpl.php

<?php /*  * catchy overview block template  *  * defined vars:  * $nodes collected nodes grouped tid  * $terms taxonomy-array-map tid => name  * $imagecache_preset configured imagecache preset.  */ ?> <ul class="catchy-overview">   <?php foreach ($nodes $key => $value) { ?>     <li class="term term-<?php print $key?>">       <h2><?php print t( $terms[$key] ) ?></h2>       <ul>         <?php foreach ($value $node) { ?>           <li class="node node-<?php print $node->nid ?>">             <?php               $image = theme_imagecache($imagecache_preset['presetname'], $node->field_photo[0]["filepath"], $node->title, $node->title);               print l($image . "<span>" . $node->title . "</span>", 'node/'.$node->nid, array('html' => true));             ?>           </li>         <?php } ?>       </ul>     </li>   <?php } ?> </ul> 

the term translated , printed within <h2> taxonomy-term grab sql-query:

  $terms_result = db_query("     select tid, name     {term_data}     vid = '".variable_get('catchy_overview_vocabulary_id', false)."'   "); 

i hope can me out. if need more information, don't hesitate comment… i'm quite confused right now.

you cannot pass variables parameters t() function, has actual code-based string.

you can go here: drupal t() function api, read more, far know isn't possible. need find other way of translating keys. maybe making own relationship table , translate them yourself.
