Thanks for that, but what does concatenation mean and where have I used it?

Subject: Re: errors
those errors mean that the variable you're trying to print out holds no
value.
ie, this would cause such an error:
$bar = $foo . 'quux';
since I didnt assign any value to $foo, it will say i usded an unitialized
variable.
a little pointer for readabillity of your code; instead of escaping all your
double quotes in the print statement, concider this:
print qq(Your E-mail:<input type=text name="email">
value="$INPUT{'email'}"><br>\n");
the 'qq' means 'double quote this next string'.. it does the same as
normally putting " " around a string,
except now perl wont get confused on what you mean =)
