Scott - when I run the above code, I observe the following error message when I press the Let's Play (or okay) button
Error using test1>start
Too many input arguments.
Error while evaluating uicontrol Callback
This is because the function signature for start is
function start(basebet)
which is expecting a single input parameter only, and there are probably at least two parameters being passed in (by default) - an object handle, and some event data. Since you want this function to have access to basebet, then I would do the same thing for this function as you did for storebet: create start as a nested function within test1 so that it has access to the local variables declared within this "parent" function, and change the function signature and body to
function start(source, callbackdata)
% do something with basebet
basebet
end
Note that in the above, source will be the handle to the push button (so will be identical to the handle okay), and that callbackdata will be empty.
