I'm getting a few different answers online to what this message is. So far, no luck. Any idea what I could be ignoring or not considering?

Hi @dylanA,
check your "STUDY" variable, most likely you have one or more missing.
You should filter your variable to exclude those lines where you are missing the study reference.

A tip:
Do not use double quotes as a variable name, as I see in the screenshot you attached, you may have problems.
If you create a filter like:
"STUDY" != "" (It won't work)
but if you just call it STUDY or other name (don't use special characters) with:
STUDY != "" Will work and you will be able to see your analysis.

Cheers,
Maurizio

fun fact,

you can use special characters if you wrap it in backticks. so you can go:

`"STUDY"` != ""

note that backticks are not the same as an apostrophe or 'single quote'. you'll (typically?) find the key for them below your escape key.

cheers

Hi Jonathon,
you are right to mention the possibility of using backticks to wrap special characters.

I wonder, why mess with special characters for variable names?

I didn't give this tip, specifically, because Windows users with an Italian keyboard are forced to use the numeric keypad to enter ` (ALT + 96), but what to do when using a laptop?
Perhaps the "simplest" solution is to remap the keyboard like Linux, since Linux allows you to type ` by pressing ALT + ' (ALTGR + apostrophe).

Cheers,
Maurizio
