I am trying to create a dynamic hyperlink within a mail merge document, and
am having problems getting it to work.

The URL is a combination of the HyperlinkBase from the document properties,
a page name from a mergefield, and am just appending the .htm extension as
follows:

{ Hyperlink {DocProperty HyperlinkBase} {MERGEFIELD Course_id} ".htm" }

However, when the merge runs, all i get is the Hyperlink base as the URL -
no page name.

Can anybody let me know what i'm doing wrong.

Many thanks in advance
