Script returns error for some users

Question

I tried (first time) to tag some caches to existing scripts.

This one <a href="http://project-gc.com/Challenges/GC3A4N3/15243">Project-GC Challenge checker</a>

should be OK but if I check my configuration in the tag it returns errors for some users.

 

Can anyone please tell me what might be the reason:
Error is:

Array
(
    [lineNo] => 102
    [error] => attempt to concatenate field '?' (a nil value)
)

Answer 1

Very probably an error in the script due to particularities in that user's set of finds. Tell the author of the checker (listed on the checker page) about what users fail.

Comments

The error is caused by the fact that some users have not found one of the types mentioned in the 40% requirement. The script wants atleast one cache per type found.
