Category links not working in left most collums

Hi Jelcke de Boer,
To change the url at this block, you must update file catalog.xml under the path app\design\frontend\default\jm_book\layout
Find the line of code:

<reference name="left">
 <block type="core/template" name="left.permanent.callout" template="callouts/left_col.phtml">
 <action method="setImgSrc"><src>images/media/col_left_callout.jpg</src></action>
 <action method="setImgAlt" translate="alt" module="catalog"><alt>Our customer service is available 24/7. Call us at (555) 555-0123.</alt></action>
 <action method="setLinkUrl"><url>checkout/cart</url></action>
 </block>
 </reference>        
     

and if you want to http://staging.amstelbooks.nl/monographies.html you must change url to

<action method="setLinkUrl"><url>monographies.html</url></action>

Then click Save file catalog.xml
Go to backend to reindex data and refresh your cache. Your link will be fine in frontend
I hope my answer could help you.
Tks and br
