Remember that a hash is a datastructure where each element has a *key* and a *value*. Looking at your code I think your intent was to create a hash (%dataoptions) that had one key "Gender", and that key "Gender" having a related value that is an array whose elements are "Male" and "Female".
So, this:
my %dataoptions = (
"Gender", ["Male", "Female"]
);
should be this:
my %dataoptions = (
"Gender" => ["Male", "Female"]
);
The other thing to remember is that this:
["Male", "Female"]
creates a *reference* to an anonymous array. So in hash %dataoptions, the value corresponding to key "Gender" is a *reference* to an anomyous array containing elements "Male" and "Female". So then when you do
foreach $option ($dataoptions{$columns[$i]})
$option is a *reference* to an array.
I think you want your loop to be something like this:
for ($i = 0; $i < @columns; $i++)
{
print $columns[$i].': ';
my $arrayref = $dataoptions{$columns[$i]};
foreach $option (@$arrayref)
{
print '<input type="radio" name="'.$columns[$i].'" value="'.$
+option.'"> '.$option.' ';
}
}
HTH.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
