I am developing a shipping extension. I would like to add a link under shipping label on onecheckout page. I tried putting some rewrite for block like:
<blocks>
<modulename>
<class>Company_Modulename_Block</class>
</modulename>
<checkout>
<rewrite>
<onepage_shipping_method_available>
Company_Modulename_Block_Onepage_Shipping_Method_Available
</onepage_shipping_method_available>
</rewrite>
</checkout>
</blocks>
I created the block as well and extends it with "Mage_Checkout_Block_Onepage_Shipping_Method_Available" and override getCarrierName($cc). But it is not working, Can anyone help, thanks in Advanced.
