Bit of a problem with the following error message using jquery 1.6.4 and jquerymobile version 1.2.0:

1. Uncaught TypeError: Cannot call method 'format' of null

The above error does not occur when navigating to a specific page on first load. It only seems to happen once I navigate from my main menu to another page then back to my main menu and then on to a different page.

Any ideas? I have added in:

1. <div data-role="page" id="makeclaim" data-url="@Url.Action("MakeClaim", "AllowanceClaims")">
