Problem formatting list with JSON

[hrt13]

The following code in my JSON formatting file causes the list to disappear,

"txtContent": "=if([$Medium] == 'In-Person', 'Reason for requesting in-person: ' + [$in_x002d_personjustification], '')"

If I remove [$in_x002d_personjustification], or replace it with text, i.e., '[in_x002d_personjustification]' the list works with the correct formatting.

I have tried removing all records and creating a new one with a value in [$in_x002d_personjustification] (column name, "in-person justification"), the list still does not appear. I have seen this happen when the column name doesn't exist in the Sharepoint list, but that doesn't seem to be the problem here, unless I'm missing something.

UPDATE: I just tried creating a different column (this one I named reason), putting some text in it, then changing the JSON, the preview worked, but when I saved it, I got the same problem.

@hrt13 try [$in_x002d_personjustification.Value]

@BB-SPDevjust tried it, same problem. Thanks though. I realized I should have mentioned the column holds multi-line text items.

@hrt13I just figured it out. I had to "Edit the current view" and check the "Display" box next to the column. Hopefully, I'll remember that next time.

You need to access the data from another column using it's internal name like: 

[$InternalNameOfColumn]

Also, make sure that you have added all the columns you are using in JSON formatting in your list view. (From list view settings).

@ganeshsanapthanks for the response. I was using the internal name for the column, but I forgot to "display" the column., (as I said in my last post). Thanks for responding though.
