Undefined Runtime error issue

Hello, I’m facing Runtime Error with undefined text.
I’m unable to understand why this is appearing and how to fix this. Those blocks are working fine but still that error comes.

Whatever I do with this button block. this error comes.

Show the blocks of the procedure you created and any more blocks if you have

You created a variable and used it in blocks. Then you changed variable’s name or deleted it, that’s the reason.

Make sure you are using when any card view clicked event…

If so then differentiate the clicks or component by using if then else block
