Hi!

I never used our, so all this looks a bit strange for me :-). Anyway, try the following:
Change this 

 
our(@ratio, @ratiobox, @concentration, @wtPercent, @density, %chemname
+);
my (@concentrationbox, @densitybox, @wtpercentbox);

[download]
to this: 
our(@ratio, @ratiobox, @concentration, @wtPercent, @density, %chemname
+, @wtpercentbox);
my (@concentrationbox, @densitybox);

[download]
And this: 
map{$_->configure(-textvariable=>\$wtPercent[2])}@wtpercentbox;

[download]
to this: 
map{$_->delete(0,'end')}@wtpercentbox;
for my $i (0..$#wtpercentbox) {
        $wtpercentbox[$i]->insert('end',$wtPercent[$i]);
}

[download]
It should work now (I hope so :-))
