    Regexp_Extract generating 'null' values

    tancrde.fde

      Hi,

       

      I am trying to use regular expressions with Tableau to capture a sub-string from another variable but whenever I use 'Regexp_Extract' I get null values. Oddly enough, when I use 'Regexp_Match' and 'Regexp_Replace'  Tableau understands the regular expression I input. I am trying to get he first part of the url path.

       

      See the screenshot:

      I have tried to change the data source from a Google Analytics extract to an excel spreadsheet but not to no avail.

       

      Thank you for your help.
