find the language of a device and use it as a condition

[alberto197103]

Hi everyone. I would like to make a column visible only if the system language is Italian. then I created a visual column called "system language" with the formula " CONTEXT("DeviceLocale") " and then a column "IT" with the formula "text" and the program " IF(LEFT([system language], 2) = "is", TRUE, FALSE)". Unfortunately it doesn't give me anything back and I don't care if I get the first or second formula wrong. Does anyone know and can help me? Thank you
to search for the language I also tried the formula " CONTEXT("Locale") " but without success

Just set the IT column to YES/NO type and use an expression USERLOCALE()="Here, use a string that matches Italian locale"
