Welcome to RootsChat
May I suggest that you explore the Scotlands People website. Link provided below.
https://www.scotlandspeople.gov.uk/I would recommend that you register and if you wish to view any records it will be necessary to buy credits. The cost depends on how many you wish to buy.
This is the information about Credits:-
Most purchases are made using Credits which cost £0.25 each and are available in batches of 30 (£7.50) or 40 (£10).
All credits are valid for two years and will expire at the end of two years unless further credits are purchased in that time.
It's free to register on the site.
