Hi Kim,

You can do this by adding a picture switch to your mergefield.

To do this:
. select the mergefield and press Shift-F9 to expose the field coding. It
should look something like
{MERGEFIELD MyTime}
where 'MyTime' is your mergefield's name.
. delete anything currently appearing after your mergefield's name and add
'\@ "h:m am/pm"', so that your field looks like:
{MERGEFIELD MyTime \@ "h:m am/pm"}.
. if you want the hours and minutes to display leading 0s, change 'h:m' to
'hh:mm'.
. press F9 to update the field.
. run your mailmerge.

Cheers
