Is there a criteria where the the field you've selected to view in the form header won't display? In all of the examples it works with a 'Status' field, but when I try to change to any other field, it won't work. I thought it was fields that had spaces in them, but I've just tried with a simple field named ID (it's the title field) and it still doesn't display. I'm so confused why it would display some fields and not others?
"children": [
{
"elmType": "div",
"txtContent": {
"operator": "+",
"operands": [
"Job Number: ",
"[$ID]"
]
},
