No directions, "to here" "from here"

[travb]

I just created my first map, and there is no "to here" "from here"
link, so I cannot calculate distances.

Why is the "to here"/"from here" not showing up?

On each marker, under the "Details" tab when you are editing the marker please make sure the " Provide a link for driving directions" checkbox is checked.
