Hello, this concerns the checker for the cache GCBMEHJ.
Initially, a checker was created that was intended to verify completion of a matrix. However, the cache was not published. Consequently, I modified the listing, and it became an attribute-based challenge checker. Now, if you search for the checker using the GC code, you will find both checkers listed.
Please delete the checker associated with the matrices.
https://project-gc.com/Challenges/GCBMEHJ/113303
If you check the "Note Logs" section on the Project-GC page, both checkers are displayed. This should not be happening.
Thanks in advance.

[New] Review of checker for GCBJ1TJ. (1 reply)

Joolay — Mon, 25 May 2026 01:14:36 +0000

Hi KaiserVonChina my apologies the output for this checker is not quite correct.

It was to have been Cache-to-Cache elevation of 1000km or more. so two caches have to be 1000km apart, If that makes sense. Currently it’s just showing Joolay](https://www.geocaching.com/profile/?u=Joolay) has used [Project-GC](https://project-gc.com/Challenges/GCBJ1TJ/113647 "Project-GC Challenge Checker") to see if they qualified for this challenge and they did.

I have travelled for **1149910m (1150km)** of elevation

Rather than the required distance of 1000km of elevation between caches.

This is my fault for not realising and picking this ip before publication.
Is it possible to fix this.
Regards Julie

[Resolved] GCBC2VM Elevation / State X 20 Challenge (2 replies)

CheekyBrit — Sun, 24 May 2026 23:27:12 +0000

Hello good sirs and or madams.

May I please have a challenge checker made for GCBC2VM.

The challenge is to have found at least 20 combinations of U.S. state (including Washington D.C.) and elevation (in 1000' bands). For the 1K elevation bands, these are spanning less than or equal to 0', 1-1000', 1001-2000', all the way up to the geocaches above 14001'. It doesn't matter what type, size, difficulty, terrain, found date, or hidden date any of the caches have.

Here is the outline of what folks have to play with, detailing which 1k' elevation bands each state touches:

Please include a visual grid in the output with elevation bands along the top and states down the side. Let's cap the last elevation band at >14K since only GC4C79N is in the band above (20197') and only 5 people have found it. If feasible, can we have the unavailable combos (like 3k and greater in Alabama) grayed out? This will make the possible limits more visible.
If it helps, here is a similar challenge checker: https://project-gc.com/Challenges/GCBC2QC/111698

I realize there's a possibility of impossible elevation, like a long distance Multi starting up high, finishing somewhere low like Florida but being listed as Florida. I don't think there's an easy way to mitigate those oddballs and I'm fine with just leaving them in, unless you have a burning desire to code a solution.

Thank you so much for your time and help.
Cheers,
CheekyBrit

CheekyBrit — Sun, 24 May 2026 23:16:44 +0000

Hello and good day sirs and or madams.
May I please have a challenge checker made for GCBC2VN.

The challenge is to have found at least 80 combinations of hidden day of the month (1-31) and elevation (in 1000' bands). It doesn't matter which month or year caches were hidden, so for this challenge May 4th 2026 and April 4th 2025 would count as the same hidden date. For the 1K elevation bands, these are spanning <0', 1-1000', 1001-2000', all the way up to the geocaches above 14001'. It doesn't matter what type, location, size, or found date any of the caches have.

Please include a visual grid.

This checker looks for a find in each county to get a list of counties for all 26 letters. It has special rules for Q, X, and Z as these are either rare or non-existent in counties. User chillo7 is not showing an E find in Essex county despite having made several.

https://project-gc.com/Challenges/GC7V6AB/36287

Debug output shows:
Mmaricopa county (az)
Ddekalb county (ga)
Kkings county (ny)
Xbaxter county (ar)
Nnapa county (ca)
Ssolano county (ca)
Yyork county (me)
Bbarnstable county (ma)
Wwindham county (vt)
Llos angeles county (ca)
Qdubuque county (ia)
Ccumberland county (me)
Jjefferson county (al)
Ggreene county (mo)
Ffranklin county (ma)
Oorange county (fl)
Aalameda county (ca)
Ppenobscot county (me)
Hhancock county (in)
Rrockingham county (nh)
20

My guess is it found Baxter county and then excluded other counties with an X from further candidacy. Essex where she has other finds is what she expected to see for E.

Can the script be made more robust given the odd Q,X, Z rules so things like this don't happen. Thanks
