Hide a paragraph, if two items are selected in a multi reference field


I have projects and want to show the name of the company and the deliverables I did. If i did more than one, I want to put an ampersand (&) between them.
So basically, I want to hide a paragraph ( “&” in this case) and only show it, if there are more than one items in the multi reference field selected.

I tried workarounds and conditional visibilities, but didn’t find any solutions.
Is it possible to show/hide one specific paragraph, if there are two items in a multi reference field selected?


I have got two collection lists:

  • Projects
  • Deliverables (Webdesign, Development,…)

Help is much appreciated. Thank you for your time!
