I tried it and it is working. Thank you for the support!
Hi,
the screenshot screenshot shows three snippets. The first one is still working. The second and third ones stopped working after I changed the value of the snipped.
When I returned back to the setting the page, the names are lowercased (the names before were datum1OCUP2Found and datum2OCUP2Found).
If I lowercase the snipped names in the text of pages and articles, it shows again the proper value. But I do not like the idea I have to change all pages and arcticles.
