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.
Thanks
