Hello, thank you, but I can not understand how to apply some parts of code on my case.

I have a Collection which looks like this: 

Collect(
ErrorCodes,
   "SOX-DOC",
   "QA-EU",
   "QA-CON"
);

So in my collection I don't have any columns it is just list of error codes.

Code which they offer is: 

Set(newOption, 
    If(
        IsBlank(LookUp(your_datasource_name, ColumnName1 = TextInput1.Text)),
        Patch(
            your_datasource_name,
            Defaults(your_datasource_name),
            {ColumnName1: TextInput1.Text}
        )
    )
)

So what should I do, If I don't have Column Name?
