[edit]Worked out its a side effect of modern ability to use named lookups
If you try and use the word last or random in the item of reporter - it is ignored
I found this out when trying to use last in my column reporter
I'm not sure where input is coming from, but I recreated your block, atleast, I think I did, is "Col = 1" a scripted menu? Based on it's appearance it appears to be. For me if I put last or random I just get an empty reporter bubble.
I'm wondering if you're assuming that the last of the other blocks in the variable category is a default and trying it that way instead of actually programming in a last option? I'm probably wrong, but for me, that's what I think appears to be happening for me atleast, because I'm getting a different result, as in, I'm getting the empty reporter because snap isn't seeing any "last" block in it's definition, so it's giving me "I don't know" as a response.
Sorry - I've corrected the examples to just use input (input was the same as data)
Aah - I think you've stumbled on what the issue was
I made this column reporter a long time ago, before Snap! allowed us to use named items as well as numbered items as lookups into lists so that explains why it didn't work like it used to
I'll just have to use my new solution
