What do you mean by "value doesn't print"?

If you want to copy the value of the previous field, where you have:

Expand|Select|Wrap|Line Numbers

//element2.value =document.getElementById().value;

Insert:

Expand|Select|Wrap|Line Numbers

 
if( rowCount > 0 )  

 element2.value = table.rows[ rowCount-1 ].cells[ 2 ].getElementsByTagName('input')[0].value;

Be careful about using childnodes, since some browsers include newline characters in the markup.
