How to get session data in custom extension block

[SandipMgnt]

Hi,

I am setting magento session but unable to get it in my block.

I have controller where session data is save into "LB_Session".

Mage::getSingleton('customer/session')->setLB_Session(serialize($_SESSION['LB_Session']));

I am getting this into controller.

But when I try to get it in block its not working.

I am calling block on add product to cart page which is called as per below

<catalog_product_view>
<reference name="product.info.addtocart">
<block type="lb/lbblock" name="lbregistration_button_lbblock" template="lb/lbregistration_button.phtml" />
<reference name="content" >
<block type="lb/lbblock" name="lbregistration_popup_lbblock" template="lb/lbregistration_popup.phtml" />
</reference>
</reference>
</catalog_product_view>

Thanks in advance

Can you specify the method with which you want to get the session Data?
