Date result

Hi all
Absolute newbie here so please excuse my possibly stupid questions that I may ask...
First one - I have tried my first rule for files in an existing folder, set the rule to rename them:
date created_name_extension
But the result was that the date created appeared 14 times!
What have I done wrong??
Thanks
Claire
