Small javascript / HTML project

This project is to create a simple HTML / javascript web page via our CMS. The page will allow users (webmasters) to generate a piece of javascript code for inclusion on their own websites. This javascript allows the user to include a widget on their own website. (Note the actual javascript for the widget itself is already written, this task relates only to generating the java scriptscript block, so that users / websmaters can get an instance of the widget for their own websites ). The HTML / javascript webpage:- - Will include a control to allow the target widget language to be selected by the user / webmaster - Will include a control to allow the target widget size to be selected - Will include an instance of the widget on the page which is dynamically updated to match current selections - Will output a block of javascript code that the user (webmaster) will be able to copy from the webpage as below <script type="text/javascript"> var widgetWidth = ***to be set based on size selection***; var widgetHeight = ***to be set based on size selection***; var language = ***to be set based on language selection***; *** fixed block of 2 lines of javascript to be supplied by us </script> IMPORTANT NOTE: HTML / Javascript must be entered into our CMS system. We will supply access details. CMS systems includes tags to allow raw HTML / Javascript to be entered on page.
