Hyperlinks in Email Body

Hi

I'm trying to add a hyperlink to the Custom Report Layout which I can create dynamically in NAV.

For example, I am editing the R1305 Sales - Confirmation report. I have added my new fields to the LetterText DataItem and I can get them to show up on the Email that is sent out.

However, when I try to make this a Hyperlink the XMLMapping is not replaced with my URL (if I insert the XMLMapping text into the Hyperlink editor) and I cannot select Hyperlink when one of the mappings is selected.

Is this possible?

Thanks in advance.
