Hi
       It is DEFINITELY not doing what it is asked to do.

The EXPECTED OUTPUT was ::
                  Resurfacing for Swimming Pools</title>
<meta name="robots" content="index,follow">Home
<meta name="keywords" content="pool 
Resurfacing,uglassit,fibre-shelkote,Uglassit,Fibre-shelkote,swimming pool 
resurfacing">Home

But the RESULTANT OUTPUT we got was ::
                   Resurfacing,uglassit,fibre-shelkote,Uglassit,Fibre-shelkote,swimming 
pool resurfacing">Home

This means that it is not picking the "Resurfacing" in the SECOND line of 
the file, but rather picking the "Resurfacing" in the FOURTH line of the 
file.
Why is the second one not picked ? This was my question.

Regards
Kiran.
