In the following code I want to use an array to place the values instead of hard coding them in. Is this possible and what is the syntax?

start_form,
"What's your favorite color? ",
popup_menu(-name=>'color',
      -values=>['red','green','blue','chartreuse']),
end_form;

Thanks,
Frank

my @array = ('red','green','blue','chartreuse);
# just pass a reference to your array
popup_menu(-name=>'color',
      -values=> \@array
end_form;

teraplane,

Being new to perl I may be missing something obvious but I couldn't get the solution to work so I went with ozo's.  Thanks for the input though.

my @array = ('red','green','blue','chartreuse);
# just pass a reference to your array
print popup_menu(-name=>'color',
      -values=> \@array),
end_form;
#or create a new reference containing your array
print popup_menu(-name=>'color',
      -values=> [@array]),
end_form;

Thanks ozo,

I have also discovered a missing single quote after chartreuse.

my @array = ('red','green','blue','chartreuse');
