following your latest screenshot we can see, that both column names Password and Mobile are correct
you also used a Mobile number in the sql statement, which is available in the table (12345)
which means, you should have received the message "Login successful"
unfortunately you did not tell us, if you got it working now
concerning your Do it results:
you already learned meanwhile (?), that you can'T use Do it together with local variables, therefore you get package result, which does not help...
also I have to assume, you first used Do it
on the label before sending the query to the fusiontable, which means, it displays the text "Result", which I guess was added from you as default label text...
so the correct sequence to get a reasonable result from the fusiontable obviously is
1. send the query to the fusiontable and wait, until a result has been provided (you will now also see the result in your label)
use "Do it" to display the result in the comment box
