Correction module export products

I based on the following module: [login to view URL] It was developed through this code: [login to view URL] The module is already running in my magento. as you can see here this is a product that was exported from magento to the sales site (this sales site is like ebay): [login to view URL] to export the product he would have to export the template with store information that is the images in blue that is already exporting. But the description does not rise in the blue template it this before and can see the link above. within the template layout there is the option to put photo. Place description, and put the title product. It is a simple module. it should work with multiple stores. All of this functioned correctly but had updated the site code (mercado livre) and therefore stopped working
