Ignition 8.1.1.

- I’ve got a table and a row _Delete_ button.
- I need to get the “id” value of the selected row on the table.
- The _Delete_ button _onActionPerformed_ runs a script which contains the line

```auto
    params = {'id':self.parent.parent.getChild("Table").props.selection.data[0].id}
    system.perspective.print(params)

```

The console reports the row with

```auto
23: ... Perspective.Designer.Workspace - {'id': 1L}
23: ... Perspective.Designer.Workspace - {'id': 3L}

```

… the ‘L’ being added, I guess, to signify _Long_ datatype.

If I change it to look at a cell that contains ‘ABC2’ I get

```auto
23: ... Perspective.Designer.Workspace - {'machine': u'ABC2'}

```

which looks like ‘u’ signifies Unicode.

How do I get just the data without the type information?

While we’re here, I can’t find a good tutorial on coding an Add and a Delete button for the table. It’s hard work! Is there a guide anywhere?

Many thanks.

Hmmm. If I use

```auto
system.perspective.print(params['id'])

```

I get

```auto
23: ... Perspective.Designer.Workspace - 2

```

which is what I want.
