Hi, I am creating a tool that provides the user with different input options based on the format of the input file. I have a conditional statement: <conditional name="fType"> <param name="file_type" type="select" label="Input File Type"> <option value="1">Type1</option> <option value="2">Type2</option> <option value="3">Type3</option> </param> <when value="1"> etc..... There is overlap between the options available for each file type and type1 and type 2 have identical options. Is there a way to avoid repetition under each <when> tag? For instance, I tried <when value="1,2"> but this doesn't work. I also want to send the file type to the program "--ftype $fType.file_type" so I want the values in each option tag to be unique.
