Okay, thanks for the advice that sounds a good place to start. I used %2.os  
was an attempt to define width and precision to stop typo errors eg the  
user accidentally inputing 101/09/2009 or similar error. So that the  
__/__/____ was adhered to.

I will go back to the start get the basics happening and then figure out a  
way to catch errors with format and correctness.
