Okay, so here is how you need to do it:

  • First set all the Airtable credentials through the property blocks, the sheet name, API key etc.

  • Then, suppose you want to use the GotCell block. First you need to register the event "GotCell" through the RegisterEvent block, like "AirtableClassic1.GotCell", and supply a function name, the function provided will have the same arguments as the event.

  • Then you would normally call the "GotCell" block, and it would trigger the corresponding procedure registered after getting the data of the cell.

Can this code get message in background and show it on the label.

Unfortunately, I dont not know the extension you are using.
The next step you have to do is to create a procedure which the numbers of arguments the "GotCell" has.

Here is the example of the Timer event in clock.

Please post your blocks, what have you tried so far?

Actually I was trying to get message and store it in a variable and when the app will open then the message will be shown on the label
But it didn't worked!
