Thanks a lot for your answer Paul! The labels are not on a Userform, but integrated on a slide (see image below). I did not understand that it is just for userforms. Is there something similar if labels are not part of a Userform, but just placed on a slide? The problem in my case is that each field you can see is a label and I have this slide multiple times. I don't want to call each label on its own, but use a loop instead such that I can access labels o_1, o_2, o_3 etc. by one for loop...
