Hi eric,
Seems like it works! it reproduces the content of the filled box.
but does this also work if it has to copy something from the previous page?

All I did was use the form to be the data producer. The form gets submitted which inserts into a database then you get redirected back to the page where the value will now show above the input. If it's in a database I can bring it into the form as a value anywhere. I can fill an input of any kind or any text.
Now the question is do you know how to write your mysql statement to extract the value that you need to display?
