Thank you very much in advance!

Happy geocaching, Seidenflamingo.

Please test and reply

Thank you very much! It works perfectly well!

However, sadly, there is a similar Challenge cache located ca. 20 km away and the Reviewer asked me to set another task. Therefore I will ask you for another checker in short time.

Thanks once again!
