So I have a column Percentage Complete that calculates when my other columns are ticked off and complete. When it gets to 100% I want the next column Date Set Up Completed to auto fill with today's date. How do I do that?
I use Zapier for this.

As Craig implied: Smartsheet doesn't enter hard-coded dates. You will have to use a third-party tool like Zapier to complete the task. They have a free version, but depending on the number of conditions, you might have to upgrade to the paid version.
To prevent the date from updating again (intentionally or not), if using Zapier, you will need a multi-step Zap - which is a paid license.
