I don't need to store the date i just want to make sure is entered correctl=
y.
I would like to have the user type the date like

21 02 2013
and then convert it to 2013-02-21 because thats how mysql wants the date in=
 order to store it.
Please show me how to write this.

Also, can you show me how to write it that if so even if the user entered d=
ate is wrong it doesn't just crash the cgi-script?i know i can use tr: expe=
ct: but i want to avoid it, somehow i need to check the date in the same if=
 statemnt like i do with the other user defined varibles for validity.

if( task and ( price and price.isdigit() and price.__len__() <=3D 3 ) and (=
 date and datetime.strptime(date, '%Y-%m-%d') ) ):

Thanks.
