The operation add items to list cannot accept the arguments: , [*empty-string*], []

blocks (11)
blocks (10)
What is the problem here?

Error most probably doesn’t come from this blocks. Some where you use add to list block

Also in join blocks you should use

blocks (12)
Yes I have used list blocks here, any problem in that blocks?

Ok I will do that !

Replace value if tag not there from empty string


to create empty list


Do you know why this comes under result?
After doing that I solved my previous error but now this is the problem

Because you are setting webviewer to go to url

In the orange line I want that google search screen
In the black line I dont want that else I want to show link of QR CODE what to do?

Then inside the cardview you must drag in the webviewer
