The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

uninitialized variables?....urgent!

Asked by Josy in Perl Programming Language

Tags: uninitialized, perl, variable

hi,
I'm posting this for a friend...

have this code which takes text "text" from a form and a number "test". It then substitutes every nth word with "_____", n being specified by
"test". When I try to run this code, it says there is an uninitialized variable at
push(@skip, $i)...? Could someone help me out...Also, would it be possible , instead of replacing each nth word with "_____" to replace it with a
textbox where a user can guess the correct word? Would someone please have code for this?
Thanks

#!/usr/local/bin/perl

require "cgi-lib.pl";

&ReadParse;

$text = $in{"text"};

$text =~ s/&/&/g;
$text =~ s/</</g;
$text =~ s/>/>/g;

$text =~ s/ +/ /g;

$count_spaces = $in{"test"};
$start = $count_spaces - 1;

$/ = "";
$* = 1;

@words = split(/ /,$text);

for ($i = $start; $i <= $#words; $i = $i + $count_spaces){
push(@skip,$i);
}
for ($s = 0; $s <= $#skip; $s = $s +1){
push(@deleted,splice(@words,$skip[$s],1,"______"));
}

print "Content-type: text/html\n\n";
print "<HTML>\n<HEAD>\n<TITLE>Cloze Test</TITLE>\n</HEAD>\n<BODY>\n";

print "<H1>Fill in the blanks.</H1><HR>";

print join(" ",@words);

print "<P><HR><H2>Answers are:</H2><P>";

for ($d = 0; $d <= $#deleted; $d = $d + 1){
$e = $d +1;
$deleted[$d] =~ s/\n//;
print "$e: $deleted[$d]<BR>";
}

print "</BODY>\n</HTML>\n";

It's called from the html form as follows...
<HR><FORM METHOD ="POST" action ="/cgi-bin/cloze5.cgi">

<SELECT NAME="test">
<OPTION VALUE="2">2
<OPTION VALUE="3">3
<OPTION VALUE="4">4
<OPTION VALUE="5">5
<OPTION VALUE="6">6
</SELECT>
<BR>

<TEXTAREA NAME="text" ROWS="10" COLS="50" wrap="true"></TEXTAREA><BR>
<P>
<INPUT TYPE ="submit" NAME="text" VALUE ="create">
<INPUT TYPE = "reset" NAME ="button" VALUE="clear">

Please help!!
