I want to hide my CMS block if customer is logged in. This is how my block is added to OPC page via local.xml
file.
<opc_index_index>
<reference name="content">
<block type="cms/block" name="cart_sinup" before="_">
<action method="setBlockId">
<block_id>signup</block_id>
</action>
</block>
</reference>
</opc_index_index>
Note: I cannot use <customer_logged_in>
because I want this only in opc_index_index page.
