Hello all, I just made my first (extremely) basic script which calculates area of polygons. The user should be able to enter the radius and number of sides of the polygon in a form, then have the area calculated. The script works fine when you type in, say, $radius = 5;. But, I want the 5 to come from the form. When I make a simple form, named "text1", I am able to get that value onto the script. But, it looks something like this ($buffer is data from form): text1=5. Obviously, I cannot multiply text1=5 times five. I want just the number from the form. Thanks.

#!C:\Perl\bin\perl

#Temporary Variables -Would normally be from form by user
$radius = 12;
$numsides = 10;

$cangle = 180/$numsides;
$pi = 3.141592654;
$halfside = $radius*sin($cangle*$pi/180);
$apothem = $radius*cos($cangle*$pi/180);
$area = $halfside*$apothem*$numsides;

print "Content-type:text/html\n\n";
print "<html>\n";
print "Area is $area";
print " when radius is $radius and there are $numsides sides.";
print "</html>\n";</p>
