| The task is now to check if the respondent uses at least one medium at least once a month. Of course, this could be done with 6 individual conditions linked using the AND operator (''and'') ([[filter-boolean|Linking Multiple Conditions]]). How this can be achieved faster and more neatly is described below. | The task is now to check if the respondent uses at least one medium at least once a month.

| **Tip:** If the item ID is only stated as a single-digit ((''TF04_1'' instead of ''TF04_01''), the ''value()'' command is not affected. This is particularly useful if the user wants to check more than 9 items. | **Tip:** If the item ID is only stated as a single-digit ((''TF04_1'' instead of ''TF04_01''), the ''value()'' command is not affected.

| In this example, it is particularly interesting what can be done with the counter (''$counter'') -- i.e. the last three lines. If an interview uses none of the specified media at least once a month, in the above example he will be sent directly to the end of the questionnaire. Of course, a question block could also be skipped in this way or other filters implemented depending on ''$counter''. | In this example, it is particularly interesting what can be done with the counter (''$counter'') -- i.e. the last three lines.
