Dear Audrey: Assuming you only want to look at Lewis' will this should help.
On the right side of the screen you should see a block that you can fill in, with what should be a number "2280 of 2280". You can type in another number in the left block and when you click on the "GO" button the website should pull up the message assigned that number. In the left block type in 1768, then click on the "GO" button.
Message number 1768 is the will of Lewis Whitfield of Townville SC, written in 1858 and probated in 1859.
