How do I access a custom variable in block.tpl.php? I created a custom module that defines a block. In hook_block_view(), I have the following code.

$block['content'] = theme('item_list', array( 'count' =&gt; $count));


How can I get the value of $count in block.tpl.php?
You have defined your block with hook_block_info(). Now you need to use hook_block_view() to add your variables to the content array which can be called in your template file.
