Passing 2 variables through browser

[Anon]

I'm having a bit of trouble passing two variables through a browser.

Here's what i've got on page 1
<a href=\"mboardadd.php?reply=true?mid=$row->mid\">[Post your comments]</a>

page2 (mboardadd.php). I tried to output the variables using:

print"
DEBUG: $reply is reply AND $mid is mboard.mid";

Here's what I get:
DEBUG: true?mid=2 is reply AND is mboard.mid

How do I get reply as "true" and mid="2" instead of everything being mixed into my $reply box?

Thanks for your help.
Mike

when adding more than one variable you use the &
