What iam missing ???
 
There is a big clue on the screen shot you have posted:

Expected Data type: IN: STRING

You have to declare a variable to be of type string to be able to pass it as a parameter of type string.

Here's an example using a DB containing a string variable:

You cannot monitor string variables as strings, you have to monitor them as a collection of bytes and display them in character format.
