Where does the second msgbox come from? What does it say? Do you need it to wait for the user to click OK in the first message box before continuing on with your code?
I usually do
uiwait(msgbox('whatever I want to say'));
but actually I've made a msgboxw() function as it's own m-file and saved it to a folder on my path.
function msgboxw(message)
uiwait(msgbox(message));
Then I just call msgboxw('hello world') whenever I need a message box that displays and waits for me to click ok before barreling on with the code.
