Hi try something like:
Code:
awk -F, -v pat="$Pattern" '
  {
    n=split($9,F," ")
    for(i=1; i<=n; i++) {
      if(F[i]~"^" pat) {
        split(F[i],VAL,/=/)
        t+=VAL[2]
      }
    }
  }

  END {
    mess=pat "=" t
    sub(/^=/,x,mess)
    print mess
  }
' somefile

If $Pattern is empty it just renders a total of all fields in $9

IGAWK(1)							 Utility Commands							  IGAWK(1)

NAME

       igawk - gawk with include files

SYNOPSIS

       igawk [ all gawk options ] -f program-file [ -- ] file ...
       igawk [ all gawk options ] [ -- ] program-text file ...

DESCRIPTION

       Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

       AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like

	      @include getopt.awk

       in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.

OPTIONS

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
       }
       EOF

       igawk -f test.awk
