Changing dropdown from a table

[Civize 3]

Hey guys. 

 

Ive been working on a bot that logs into a website using the first 2 columns of a table as username and pass. Once it's logged in, it requires that i enter a Date of birth (DOB) for each account and the DOB for each account is different. I have the account info in my txt in this format:

 

username : password : day : month : year

 

And the place where i have to enter the Date Of Birth is a dropdown. How can i change the dropdown using my table? Any help would be greatly appreciated
