Timer doesn't work

Question

Hi,
I copied the code from the sosci website to set a timer to show the "weiter" button. Before it always worked, now it shows the following error:

There is an error in the PHP code:
Questionnaire Error: Command or string (text) unfinished

A command, e.g. question() is missing a semicolon or
a string (text in quotation marks) is unclosed or
the string itself contains an apostrophe, e.g. html('Let's do it!'); – if the latter is the case, please type in a backslash () first.
Perhaps the opening and closing braces for the statement blocks are mismatched.
PHP code

001 namespace s2survey\questionnaire\environment;
002
003
004 <!--
005 SoSciTools.submitButtonsHide();
006 window.setTimeout(

This is the code I used:

<!-- SoSciTools.submitButtonsHide(); window.setTimeout( SoSciTools.submitButtonsDisplay, 20000 ) // -->

Please make sure to distuingish between PHP code (which runs on the server) and JavaScript code (which runs in the browser). They are to be embedded differently:

• Introduction to PHP
• JavaScript in the Questionnaire
