Hello Alteryx Community,
I'm trying to concatenate two fields together to make 1 address line, which I know how to do if the data is in the right fields. However the data I want to use is split across three fields but I don't to use all of it.
In the screen grab below, I want to concatenate the contents of the building number field with the Thoroughfare_and_descriptor field (street name).
However some of the building numbers are in Building Name field. Where this happens I only want to concatenate the numbers and not the names with the Thoroughfare_and_descriptor field (street name).
Any suggestions on how I can do this please?

Thanks in advance,
