Information from South African ID

Information from South African ID

Hi there

I am referring to the post made 3 years ago.  I need to calculate the Date of birth and Sex form a South African ID Number

https://help.zoho.com/portal/en/community/topic/extracting-usefull-data-from-south-african-id-number

I am not sure where I need to insert the required information, also I need to adjust the code to suite my field names:

I have an ID Number Field (ID_Number) and then a Date of Birth Field (Date_of_Birth) as well as a Male / Female option box (Sex1)

Hope someone will be able to assist me

Regards
