Which function would you use to extract the word "casual" from the product name "casual pants" of the Product Name field?

Left(5; [Product Name]) reverses the required parameter order - the string field reference must be the first argument and the numeric character count must be the second.

Left([Product Name]; 5) is the only option with correct Web Intelligence formula syntax - the field reference in square brackets is the first parameter, the numeric length is the second parameter, and a semicolon serves as the argument delimiter as required by the Web Intelligence formula language. While the value 5 extracts only the first 5 characters, this option is correct in demonstrating the required syntax and function selection.

Right((Product Name), 5) uses the wrong function since Right() extracts characters from the end of a string, and it incorrectly uses parentheses instead of square brackets for the field reference and a comma instead of a semicolon as the delimiter.

Right(5, [Product Name]) uses the wrong function and places the numeric argument before the string field reference, violating the required parameter order.
