problem solved! & new question ...
yes it does! Thank you Ray!
So what would you suggest? Is it better to create the recordset AFTER the update?
I usually try to avoid a manual copy / paste to and from parts of the code, the more if I don't really understand all the functionality behind it.
And as mentioned before, changing one line in the code manually (the thing with $WA_redirectURL = $_SERVER['PHP_SELF'];) made the multiple update behaviour disappear from the server behaviour's list which means, no more easy updates if some parameters should change.

My next question refers to the multiple delete s.b.
Would it be possible to COMBINE the multiple update with the multiple delete s.b. on the same page?
I tried this but found that the multiple update behaviour had "eaten" my prepared checkbox for the delete behaviour. It changed its name from check2delete to check2delete_<?php echo $RepeatSelectionCounter_1; ?> so that the name did not appear in the list of form elements. (I like the icons!).
So delete did not work, even after removing the "_<?php echo $RepeatSelectionCounter_1; ?>" part.
