Hi Tim

Just use the Custom Field under the Configuration > Checkout settings. If you use the Single page checkout mode, I think the placement might be acceptable.

Thanks!

Great! Thanks Stephen.

By the way, could you please so me how to refer to that custom field by using XSL Token?

Cheers,

Tim

Suppose your calendar has the ID "MyCalendar", then you can query it in your email receipt template like this. Please note the default email template should already print out all the custom fields.

{xsl:value-of select="in/salesOrder/dynamicFormResult/fields/field[@id='MyCalendar']" /}
