Dashcode Widget for 'URL'

Question

In Dashcode [latest version of xCode] I have created a widget which when 'Run' in Dashcode opens the Webpage. When dragged into iBooks Author as a URL Widget and tested in iBooks Author it will open the Webpage when loaded onto the 'First Generation' iPad in Preview mode and you tap on the Icon/Image a grey screen opens and top left the 'X' to close and nothing else happens.
This is the code for the event handler in the Widget.
function myClickHandler(event)
// Values you provide
var websiteURL = "http://en.wikipedia.com/wiki/Air_New_Zealand"; // replace with the website URL to show
// Show website code
widget.openURL(websiteURL);
If required I can post all the code however I thought that would not be necessary given that the above is the only changes I have made.
Help is always appreciated.. Ant

Answer 1

Thanks for that information but I have not been able to progress my issue. Perhaps you could send me a working example of the dashcode and I test it to see if it works on my iPad - iBooks Author. It would then be a simple process for me to change the URL [http://] at least it will determine where the point of failure is..... my address is [email protected]..
And these are a copy of the code:
