Although it is the `button` node, it is more to do with the message coming out of it.
This is the node code:
```auto
[
{
"id": "89af2b10f87e66e9",
"type": "ui_button",
"z": "f6a2d75e7dd8f7ed",
"name": "",
"group": "66644b9721f1197e",
"order": 0,
"width": 0,
"height": 0,
"passthru": false,
"label": "Start",
"tooltip": "",
"color": "",
"bgcolor": "",
"className": "",
"icon": "",
"payload": "TRIP",
"payloadType": "str",
"topic": "TRAIN",
"topicType": "msg",
"x": 350,
"y": 370,
"wires": [
[
"0f5725cd2cbfc233",
"a5d2da0031c49502"
]
]
},
{
"id": "66644b9721f1197e",
"type": "ui_group",
"name": "Control",
"tab": "530b9cb957853dd9",
"order": 1,
"disp": true,
"width": "3",
"collapse": false,
"className": ""
},
{
"id": "530b9cb957853dd9",
"type": "ui_tab",
"name": "Track Singal NEW",
"icon": "dashboard",
"order": 43,
"disabled": false,
"hidden": false
}
]
```
The `topic` field is set to `TRAIN`.
But this is what I see when I press it:
Where's the `topic`?

Change the topic to string, not msg

Hi @Trying_to_learn Maybe you need to define first the msg.TRAIN property. Because you are asign msg.TRAIN to msg.topic, and msg.TRAIN is empty.
I share some examples:
Code:
```auto
[{"id":"ad061c48fbfd7f1a","type":"tab","label":"Flow 10","disabled":false,"info":"","env":[]},{"id":"7c08f886948a062c","type":"ui_button","z":"ad061c48fbfd7f1a","name":"","group":"1839522db6d21ee9","order":0,"width":0,"height":0,"passthru":true,"label":"button","tooltip":"","color":"","bgcolor":"","className":"","icon":"","payload":"TRIP","payloadType":"str","topic":"TRAIN","topicType":"str","x":850,"y":160,"wires":[["913cc5d5b3e72bcd"]]},{"id":"913cc5d5b3e72bcd","type":"debug","z":"ad061c48fbfd7f1a","name":"debug 14","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","targetType":"full","statusVal":"","statusType":"auto","x":980,"y":160,"wires":[]},{"id":"ec7f6b08633360bf","type":"inject","z":"ad061c48fbfd7f1a","name":"","props":[{"p":"payload"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"","payloadType":"str","x":730,"y":160,"wires":[["7c08f886948a062c"]]},{"id":"94a47739bd802c06","type":"ui_button","z":"ad061c48fbfd7f1a","name":"","group":"1839522db6d21ee9","order":0,"width":0,"height":0,"passthru":true,"label":"button","tooltip":"","color":"","bgcolor":"","className":"","icon":"","payload":"TRIP","payloadType":"str","topic":"TRAIN","topicType":"msg","x":850,"y":100,"wires":[["a6bf3b5257831bab"]]},{"id":"a6bf3b5257831bab","type":"debug","z":"ad061c48fbfd7f1a","name":"debug 15","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","targetType":"full","statusVal":"","statusType":"auto","x":980,"y":100,"wires":[]},{"id":"760c8d269517f784","type":"inject","z":"ad061c48fbfd7f1a","name":"","props":[{"p":"payload"},{"p":"TRAIN","v":"this is the topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"","payloadType":"str","x":730,"y":100,"wires":[["94a47739bd802c06"]]},{"id":"1839522db6d21ee9","type":"ui_group","name":"Default","tab":"7394f2f3aeaeeb2d","order":1,"disp":true,"width":"6","collapse":false,"className":""},{"id":"7394f2f3aeaeeb2d","type":"ui_tab","name":"Tab 1","icon":"dashboard","disabled":false,"hidden":false}]
```
I hope it can helps you!!

When did this get introduced?
It may explain why a lot of stuff has stopped working recently too. ☹😢

Thanks both for the replies.
Seems I really stuffed myself up there.
Appreciated.

I don't think the default setting has been changed, but in anycase it wouldn't alter any existing buttons

Well, maybe it hasn't "back rolled" to existing things, but I am writing a lot of stuff just now and it is failing _hand over fist_ as in I am pressing buttons and things NOT happening.
I was simply doing what I always did and _not seeing_ the qualifier has changed from `text` to `msg` so never even thought of seeing it.
(Familiarity blindness - I guess)

TBH I probably copy nodes more often than add new ones, so the text setting gets carried to the new node.

I'm torn doing that only in that if the _structure_ (more so for `function` nodes than `button` nodes) it spreads bad formatting/code.
I would like to type things so I develop the _muscle memory_ on how to do things the _better_ way rather than copy/paste.
There can be nasty things propagated that way too.
But, I do get what you are saying.
