We wish to install this module to CRELoaded 6.2: [login to view URL] ...or, any other module which will allow this simple function: When a product has product options/attributes, and these attributes have prices assigned to them, we want the main price on the product_info page to update immedietely if visitor selects a product option. This update will occur using javascript onchange event. You will get FTP access to complete this task, and we need FAST turnaround time! NOTE: Please remember that the module shown above was designed for oscommerce2.2 and not creloaded, so if you are using this module as your basis, be aware you will probably need to customise it.
