Now I am creating a module for magento admin page.Below is the screenshot
What I want to do is if I select "Template" in Dynamic block i want to get that option value and pass that value to the next "Text and images" tab(tab controller)
I don't know how to get that value and pass value to tab controller.
Here is some example code I want to pass the value in URL
$this->addTab( 'dynamicpages' array( 'label' => Mage::helper('agile_dynamicproductpage')->__('Text and Images')
