Hi Brethren,
I am trying to count the number of times "trigger words" held in an array appear in a text file held in a hash.
The lines of text are split into sentences and held separately in the hash. If the trigger word occurs more than once I would like to be able to count multiple occurrence of the same word.
Got so far but am now a bit stuck! 
foreach my $key2 ($keys %UnNum){
        foreach my $word(@midWords){
            if $word == $key2 {
            $UnNum{$key}++;
            }
        }
}

Any pointers where I am going wrong would be much appreciated This is the content of the Array the trigger words
bodi
forc
twice
mass
acceler
law

The content of the %UnNum is in the format 
35    forc two bodi twice strong on bodi sai bodi mass 
39    you expect on think new bodi made two bodi origin 
60    attract bodi b origin force
46    total forc b twice origin force
34    sai on bodi twice mass three time mass forc six 
17    on now see why bodi fall same rate bodi twice

I would like to increase the value for each line by 1 for each occurrence of "bodi", "forc" "twice" etc. First line value up by 5 to 40
40     forc two bodi twice strong on bodi sai bodi mass 
41     you expect on think new bodi made two bodi origin

Hope that helps to explain better.
