Hi there,

Iam trying to make a sorting based on a counter but it seems that i get messup because when i try to sort some based on for example "3" all number that have a "3" will sorted as well and i dont want it. How can I sort ONLY the "3" and not the 13, 33, 23, 53, etc?
heres the code iam using

if (\$yixa2 =~ 3) {
\$tdtag3 = "</tr><tr>"; }
else {
\$tdtag3 = "";
}

Any ideas?

It seems that you would best be served by placing this into a hash, then sorting the hash values by number.

For purposes of example, I am going to create a hash; you would use your own data here.
my %values;
\$values{23} = 'caption0';
\$values{13} = 'caption1';
\$values{33} = 'caption2';
\$values{3} = 'caption3';

You could then use this code to print the :

foreach(sort {\$a <=> \$b} keys %values) {
print "<tr><td>\$values{\$_}</td><td>\$_</td></tr>\n";
}

This would yield:

<tr><td>caption3</td><td>3</td></tr>
<tr><td>caption1</td><td>13</td></tr>
<tr><td>caption0</td><td>23</td></tr>
<tr><td>caption2</td><td>33</td></tr>

Which is what I think you're trying to accomplish.

Otherwise, if you're only trying to find the value "3" by itself, you can use the expression,

if (\$x == 3) {
#do action
}

Good luck.
