Hi,
Regular expressions (built either using /slashes/ like you do, or with the RegExp constructor) are not Strings in javascript, so you cannot just concatenate a string (row.prime) with a regular expression /\w+/). You can, however, pass a literal string to the RegExp constructor, which it will interpret as a pattern to build the regular expression: getTextInput("response").test.text( new RegExp(row.prime+"\s+\w+", 'i') ) (I added \s+ to require at least one space after the prime, and used 'i' to make it case-insensitive, assuming it shouldn’t matter whether the participant uses upper- or lower-case)
