Bad arguments to AddMessage

In the programme there is an error message called “Bad arguments to AddMessage”. I controlled the blocks but I couldn’t find the reason of the error. Which blocks should I control again? What is the reason of the error? Can you help me, please?

show us your blocks… your error is clear to us

What page blocks. The one on the page I showed the picture on? What is clear to you?

The clearview is, You are not using list items instead you are using arguments so the app throws error…

My Blocks

Ofcourse… If possible let us know when you are getting such error? On button click or durimg screen init or something else… Pls mention it…

Again thanks​:blush:
The error occurs when button clicks
