Im beginner to magento and i wanna know how to add an attribute using setup script to existed group (Catalog ==> Manage Products ==> select a product and go to prices thats the group)
is the any way to do that ?
You can simply drag and drop your attribute to price tab under catalog -> manage attribute sets
Here i have added wholesale price to an existing price tab

See this thread for adding attribute programmatically
