The latest NorPrice uses jQuery to display the popup currency window. This may conflict with other JavaScript libraries. This isn't a problem usually as Actinic doesn't use any such libraries. However you may have added something that uses MooTools or similar.
To fix this do the following:
Make sure that in your overall layout the line “<actinic:variable name="NorPriceSupport" />” comes after your MooTools stuff. Just above </head> should do that.
Edit file greybox.js (in your Site folder).
Replace all occurrences of “$” with “jQuery”.
At the very top add the line:
$.noConflict();
This line should now be the only line with “$” in it.
Save the amended file.
See http://api.jquery.com/jQuery.noConflict/ for information on why this is needed.
An alternative might be to find a jQuery based way of doing what you’re doing. Then you'll only need one library loaded which will be more efficient.
