There is no cache at the posted coordinates. These are just the coordinates for "Vejle".
To find this cache you need to know the tracking code of the stamp I use very often to log geocaches.

To find this cache you need to write all letter values of the tracking code of my stamp after eachother.

Use a two digit value for each letter.
For example. If the code would be ABCXYZ you would write:
01 02 03 24 25 26. The resulting number is: AB CD EF GH IJ KL

Use these values in the following formulae

N55 4(B-A).(D-F)(D+J)(J-I)

E9 3(C).LEK
