I am trying to check the value a user enters into a textbox in the App Designer interface. The value the user inputs must be between 0 and 1.

value = app.EditField.Value;
if (value >= 0 && value <=1)
% call function
else               
msgbox("Value must be a value between 0 and 1.");
end

This is not working correctly. For example, if I enter 0 or 1, it outputs the message. If I input a value between 0 and 1 I get this error:

Operands to the || and && operators must be convertible to logical scalar values.

How can I fix this? Thank you.

I suspect the edit field is outputing text.

Just use Edit Field (Numeric) instead of Edit Field (Text) from the Component Library.

You can also confirm Edit field property in App initialization and construction section

app.EditField = uieditfield(app.xxx,'text');

I tried and its working for me.
