Using previous edit text value

I have created an edit text box that accepts only numeric values, however, when an erroneous value is submitted (i.e. a non numeric value) I would like the program to run with the last numeric value used. For instance, if someone inserted 5, then inserted "pig" I would like the program to continue running with the value 5. Here is my code:

[m_temp,m_stat]=str2num((get(handles.edit5,'string')));
if  m_temp ~= round(m_temp)
  m_out=round(m_temp);
  uiwait(msgbox('Please insert an integer from 0-16 in the Horizontal Lines box','Error'));
elseif m_stat==0
  uiwait(msgbox('Please insert an integer from 0-16 in the Horizontal Lines box','Error'));
else m_out=m_temp;
  if m_out>16
      set(handles.edit5,'string','16');
      uiwait(msgbox('Horizontal Lines must be integers from 0-16','Error'));
      m_out = 16;
  elseif m_out<0
      set(handles.edit5,'string','0');
      uiwait(msgbox('Horizontal Lines must be integers from 0-16','Error'));
      m_out=0;
  end;
end;
m=m_out

Where is this code? Inside some callback? You will have to validate the number, and if it's valid, save it into a "global" variable (some variable that you can access - see the FAQ), such as a structure called UserSettings or whatever you want to call it. Then the next time a number needs to be validated, if it's not valid, display an error message if you want to, but don't update your validated global variable.

Making a global variable did it. Thanks for helping a newbie.
