Easy Chart

I’m trying to get this chart to do fast polling and to use this WHERE snippet but I keep getting errors saying incorrect column name which doesn’t make sense.

I also wonder why I get an error about word 20 in the diagnostics and when I remove the brackets around it, I don’t but then it doesn’t work.
The viewer works with the error but not without it.
I think there are so issues here with this easy chart.

I can’t solve your easy chart problem, but I can point out that spaces in your column names is not considered a good idea. It works yes, but it makes all sorts of programmatic queries more ‘fun’.

Thanks Dravik,
I understand but this particular column I cannot control the naming.

Put double quotes around the column name:

“word 20”
