Hi @tonyv
When using the 'TestFilter' transformer, you will only have a few logic values to choose.
It's not until you add another test clause where you will have more options
In the example below, I required the 'four_wheel'drive_tracks' and the 'vehicular_tracks' to be grouped together and pass through the Output port which I have called 'Tracks' therefore have used the logic 'OR'
Hope this helps
I suspect the AND and OR clauses only appear once you have more than one clause defined. If you only have one clause, like a = 5, then there is no AND/OR possible. But if you have a=5, b=7, now you can start to add AND or OR.
Also note that you can type into the Logic field, so you can type AND, OR, NOT, and any brackets you might need, without selecting them from the list.

Thank you very much for this reply. Yes I now realise my lack of knowledge is the problem rather than a software issue.
Thank you again
