 ===== Example 2 =====
-A onetime probe is also possible if the respondent does not answer a question with the help of //repeatPage()//. In the following example, it is checked if a valid option in the selection question ''BB01'' was selected and if the items in the scale ''BC01'' were answered in full.

-If one of the questions was not answered in full, the text element "error_missing" is displayed and the page repeated. However only once, as was ensured with ''registerVariable()'', variable ''$rPG6'' and ''isset()'' at the beginning.
+If one of the questions has not been answered completely, the text module "error_missing" is displayed and the page is repeated. But only once. This is achieved by setting an internal variable "IV01_01" to the value 2 for the first repetition. Please create the [[:en:create:questions:internal|internal variable]] in advance in the question catalogue and use the identifier of your internal variable instead of "IV01_01" in the code. If the page is called up again and the variable has the value 2, the response check is no longer triggered.
 If the questions are on page 6, the following PHP code must be placed at the top of page 7.
