Does something like this do what you want?
function ageoffirstpilotEditFieldValueChanged(app, event)
goodage = 0;
while goodage==0
value = app.ageoffirstpilotEditField.Value;
if value< 25 || value>60
goodage = 0;
prompt = 'enter age 25<= age<= 60';
title = 'Age out of range';
dims = 1;
defaultage = {'40'};
answer = inputdlg(prompt, title,dims,defaultage);
app.ageoffirstpilotEditField.Value = str2num(answer{1});
elseif value> 25 && value<60
goodage = 1;
end
end
disp('success')
end
