Tomtom waypoint assignments give errors

[ErikssonJoakim]

Hey I'm trying to create my own guide and I can't make it work. I've tried following the instructions on the wiki to create a Tomtom waypoint which doesn't work and I've also tried copying how it's written in the standard guide but I keep getting the error:

"\Addons\TourGuideVanilla\Mapping.lua:14: bad argument #3 to `format' (string expected, got nil)"

the note waypoint I'm trying to create look like this: N Sell Junk Gear |N|Vendor (47.6, 41.4)|

I've tested going to step:

C Skirmish at Echo Ridge |N|To the north in Echo Ridge Mine (47.65, 32.00)| |QID|21|

it too gives the same error.
