No worries, @BaBuuuuuu! That’s the best thing to hear, that you’re learning!
Now you can drag off of “Set members in MinesStruct” and use your “Set Array Elem” to set the new total. Just don’t break it and you should be fine!
After that, you should be able to get A COPY for your UI use! Remember, with arrays:
Get a COPY - for just getting info
Get a REF - for changing info
