Easy associative array question 1

[rdyoll]

Hi,
In my form I have a select box with the name="beverage".
I have 3 options: coffee, tea and milk. I have in my script set up an associative array:

$beverage = param('beverage');
%beverage = (coffee => 'Folgers',
tea => 'Lipton',
milk => 'DairyFresh');

foreach $_(keys %beverage) {
$beverage = $beverage{$_};
}
...and then further in the script I want to see the value chosen from the drop-down menu like this...

print "You chose $beverage.";

...but the value never changes...it's always the last item in the array...DairyFresh
Why?
Where am I going wrong?

foreach $_(keys %beverage) {
$beverage = $beverage{$_};
}

$beverage is being assigned to each value in the hash, but remains with DairyFresh as its the last value in the hash

...ok, Paul, so what would one do to have the proper selected value displayed?

 

[rdyoll]

...if I do this:

foreach $_(keys %beverage) {
$beverage = $beverage{$_};
print "$_ => $beverage{$_}\n";
}

it will return:

coffee => Folgers
tea => Lipton
milk => DairyFresh

...but outside the loop, if I do this:

print $beverage;

if the chosen value was coffee, it still prints DairyFresh
Anyone??

this looks similar to numeous CGI examples, e.g., see the beginning of

http://stein.cshl.org/WWW/software/CGI/cgi_docs.html

except, in place of
"Your favorite color is ",em(param('color')),
you might have (aso e.g.)
"Your beverage is ",em(bevergage{param('color')},
