Well, while I'm listening to Air on the G string....
In your perl script, try:
# all the scripting stuff before your [snip] goes
# first, since that appears to be working correctly.
# The line numbers shown are for instructional poipusses,
# cut them out when you try the code
1. $midifile = $fields{'midifile'};
2. if ($midifile ne ''){
3. print qq(
4. Current music file:<br>
5. <a href="$BASEURL/$midifile">$midifile</a><br>
6. (Right-click to save to your disk)
7. );
8. }
Steps:
1. set the midifile variable so it's easier to refer to
2. check to see if the $midifile variable is not
empty (not equal to an empty string). If it's not:
3. define where you're going to start printing.
Put your HTML here. You can use $variables and Perl will
recognize them by their $ sign (or @ symbol). If you want
to use a $ symbol and have it look like a dollar symbol,
escape it by putting a \ before it, like this: \$45.00.
Same with an @ symbol.
4-6 Your HTML
7. close the print qq( statement
8. close the if...{ statement
Let me know if that works for you or not. You'll probably have to close the
print statement that creates the HTML before the new code. You'll have to
"reopen" the print statement to print any HTML that follows the new code.
