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
}

All four must be an empty string. I will be pulling the values from a
MySQL database. If these fields are empty I'll be prompting for

the user and asking if they want to change it.

Ed

I'll be trying to use a routine that checks 4 seperate variables for
content and need to know the easiest method to do so. The function works

I do something else.

$linetwo
