Number Edit Box returned value

csoon1 — Fri, 04 Mar 2016 16:46:53 GMT

I have a Number Edit Box and when nothing is specified I want to assign a default value to my variable and also prompt a message. If nothing is specified (meaning user did not put anything on the number box) and I view my variable on the "watch" window on the debugger, it seems to have a value of "." but I could not get a match (see my script below):

stepSize = 10;
New Window( "",
  <<Modal,
    V List Box(
      Panel Box( "Please specify",
        H List Box(
          Text Box( "Step  " ),
          tBox = Number Edit Box( defaultStepSize ),
          Button Box( "OK",
            stepSize = tBox << Get;
          )
        )
      )
    )
  );
If( stepSize == "." | stepSize == 0 | !Is Number( stepSize ) | stepSize == "" | Is Empty(stepSize),
  stepSize = 10;
  Beep();
  New Window( "No Step Specified",
  <<Modal,
  H List Box( Text Box( "Either No Step or 0 was specified! Will use the default of 10!" ), Button Box( "OK" ) )
  );
);

What is the returned value of Number Edit Box when nothing is specified?

If( ismissing(stepSize) == 1 | stepSize == 0 | !Is Number( stepSize ) | stepSize == "" | Is Empty(stepSize),

Thanks. I can't believe I missed "Is Missing" considering I thought I tried all "Is Whatever" available on the documentation. LOL.
