Almighty perl monks,

Please forgive me for my ignorance, oh revered ones. I am a mere techsupport flunky who was kind of thrown into a new position that involves a lot of Perl. ("You know PHP, right? You can figure out Perl!" said my boss. What a cruel man.) And now, I beseech you, please offer your guidance.

I have a text file with the following line in it:

| LEVENE'S TEST FOR VARIANCES        3, 561               0.72            0.5422    |

This is an example -- the LEVINE'S TEST FOR VARIANCES comes up multiple times throughout the file. I need to suck out the column that has 0.5422 in it each time. I tried the following:

\$levene = \$4 if /TEST FOR VARIANCES\\s+(${fl})\\s+(${fl})\\s+(${fl})
+\\s+(${fl})/;

($fl = '-?\d+\.\d+')

This is obviously not working, and I am sure it is way, way off. I have poured over a couple of Perl books, but both are very vague with regular expressions. Can anyone please help a poor guy out? Thanks ever so much.

Edit by tye, replace PRE with CODE
