I have an error in this page on the printxcl() function because there
is the earlier call to include the header.php page, On line 39 of
header.php page is
this line:
header( 'Content-type: text/html; charset=\"$CHAR SET\"' );
which conflicts with the print statement in the printxcl() function.

You can't call header() after any output has been sent to the client.
And you can't redirect output in php to another page - the best you can
do is buffer the output and perhaps throw it away. However, that hides
the problem, not fixes it.

You need to restructure your code so you don't try to call header()
after output has been sent to the browser.

thanks very much,

The quick and dirty workaround is to use output buffering to defer the
sending of data to the browser until you've sent your headers.

The correct way of doing it is to rearrange your code so it doesn't
send any output before it's done sending headers.

redirect a print statement off a page so it doesn't conflict with aheader
