Its slightly hard to understand what you want but I have answered the best I can.

You have a } after ("<script>alert('Age valid')</script>"); which means that it will ALWAYS run the code below.

Label1.Visible = true;
Label1.Text = " Why are you runnning in button click if not valid age if valid than ok ";

Fix:

Remove the } from the end of this line:
else { Response.Write("<script>alert('Age valid')</script>"); }

I hope this is what you were asking.

Really difficult to figure out what's being asked here, but I believe you're trying to exit the sub at a particular point. Use "return" to exit the sub without executing any more code.
