Hi Alan - I know you posted this awhile ago, but I'm needing help with dates in bots. I need to ask for dob. When I put my expression in the regex tester, it works fine, but not when adding to my Slot Type. I'm new to bots so not sure if I'm doing something wrong. Here's what I put in which isn't recognizing a date. Any idea what I'm doing wrong? ^(0[1-9]|1[012])+(0[1-9]|[12][0-9]|3[01])+(19|20)\d\d

Thanks,
Kara
