Dear Mazi,
Thank you for your response.
1. Which Limesurvey version do you use?
2. Where did you find this code snippet?
3. Any error messages? "Doesn't work" isn't very helpful.
4. Please switch on debug mode by adding the following line to your config.php file:
Code:
$debug = '1';
Are there any additional errors reported on top of the page?
1. Versie 1.90+ Build 9229
2. On the forum:
www.limesurvey.org/en/support/forums/2-d...ding-on-other-matrix
3. No error message at all.
4. Thanks for the tip: I'll use it in future before posting on the forum.
5. no additional errors.
Fortunately "Holch" pointed me in the right direction.
Thanks for all the quick replies.
