Hi I am pretty new to programming and perl, so sorry if this stupid...but:

I have a foreach loop, to which I pass a bunch of strings hoping to create an array of values for each position in the string, and keep all that in a hash. All the variables are declared using my at the beginning of the sub. The code works, but it gives an "Use of uninitialized value $temp_array[0] in join or string at quality_cutoff.pl line 124" error. Why? 

foreach (@string_array){    
        @string=split(//,$_);
        $basecount=0;
        foreach $pos (@string){    
            $basecount++;
            $pos_score=ord($pos)-33;
            @temp_array=$base_stat{$basecount};   # line 124
            push (@temp_array,$pos_score);
            $base_stat{$basecount}="@temp_array";
        }
