Is it possible to refresh the current page with a button?

I know that a user can refresh the screen by clicking the refresh button up by the URL.  However, is it possible to put the same functionality in a button on an ASP page.

Sadly, not all users are going to know what that button up by the URL does.  Therefore, if they are told to hit the refresh button, I would like a refresh button on the ASP page with the other buttons.

I tried creating a simple asp page to handle this.  However, I keep getting a 500 error.  Therefore, I know that I am doing something wrong.

This is what I have in my page...

<!-- #include file ="..\sagecrm.js"-->
<%

//Refresh page=====================================
location.reload();

%>

Any assistance would be greatly appreciated!

PS..I want to do a page refresh because a table level script is updating some of the fields on the based on other fields on the screen and the user cannot see the updated data.
