Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hi,

I'm looking foward to retreiving a input from an html form. However one of the html form input names must be specified by a scalar variable I have, so it looks like this: 
 $INPUT->param('about$cur_num')

[download]
However when trying to use this, I get the value of below, and not the actual form input value. 
CGI=HASH(0x15d58ac)->param('about1')
CGI=HASH(0x15d58ac)->param('about2')
CGI=HASH(0x15d58ac)->param('about3')

[download]
What can I do to prevent this?

Thanks

    I'm guessing you're trying to do that within a double-quoted string. And a double-quoted string doesn't support method calls like that. Thus, you're getting the C<$INPUT> CGI object interpolated, followed by the literal string beginning with the method arrow.

    hi, here you go. 
     $INPUT->param('about' . $cur_num)

    that should get you the proper value.
