Android Question Phone.send problem

[TMa]

Why this doesn't work
Phone.Send("" & settings.numb1 , "" & settings.heat1on)

the text section works fine... (settings.heat1on) ...
but that first number part doesn't .. gives me number 1 allways
tryed to find advise from google and forum , but no results.
tryed differend kind of combinations just closes program when it is total wrong.
Is that command even written right, so is my problem that numb1 variable

You don't need the empty quotes.

What is the value of Log(settings.numb1) ?

in my program, there is settings page and there is couple of edittext box where you can add number where to send that message and another what is that message
that example code above just closes the program when I press that button.
I know that this works if I use Phone.Send("number" , "text") , but I want to use those what I put in my settings page.
If I remove quotes , It doesn't even compile
