    Why won't my Paypal widget calculate the totals on a Mac? Windows works fine.

    When a user makes their selections the Total below should automatically update.  This works fine on a PC but Mac users don't see any change.

    Edit: Actually won't work in latest versions of IE or Firefox either.

    Hi Ben,

    I do apologize for the issue that you are currently experiencing with your form. I am able to reproduce the issue when accessing your form on your webpage:

    The issue however does not occur on your direct form:

    It appears that there is a conflict on your webpage causing the calculation not to be performed in some browsers.

    Please embed your form using the iFrame embed method. This will prevent most conflicts from occurring. 

    I hope this helps, please inform us if you need further assistance.
