App Designer "Strategy" error

Hello

I am having a problem with app designer. I have marked the error place which matlab indicates. its at the end. %%Errror%%

It looks like it does not like data type that is passes into the table, but same code in script returns double and it should be fine. But it is not.

I would like to trace my variables value in app designer but i could not find how.

I have attached part of the code from app designer and error messages.

Could anybody pleaase help me?

Thank you
