ListView: Cannot Accept The Argument Error - Please Help

Hello All, I would please ask you for help, because I am already searching a long time for a mistake. In the app are ten profiles with diary entries (script: to-do list) and the code works in another app with the same content (the light version) but not with the ten cat profiles in the pro version. The error is somewhere in the code with the replacement and the Add text. If the save button is clicked, this error appears. Here are the blocks:
I downloaded all blocks, because I do not know exactly where the mistake is:

Thank you in advance! Martina

Update: Error fixed. I had a wrong selection in the Add button. Thank you. Problem solved. Have a great day!

Next time you might want to export the AIA file of your project for debugging so many blocks.
