Ed,
Assuming there will be a response from the db-tbl, here is another choice:
if ( $lineone . $linetwo . $linethree . $linefour > "" )
{
//show it to the user and ask if they want to change it
}
else
{
//prompt for information
}
Do you mean that the db-tbl will have a row of data even if the four fields
are empty, or if there is no data (in those fields) will that imply that
there is no row (and thus different code needed)?
