awk Script Output Help
My code is listed below, I'm trying to figure out what the problem is and what I can do to fix it. The output i'm getting is:



Code:
Name Low High Average
 0 0 0.00



The correct output I want is the name of the Assignment, the lowest score and highest score obtained, and the Average Score under each column. Can Someone help and point me in the right direction



Code:
 awk 'BEGIN{

FS = " "

print "Name Low High Average"

i=0

}

{

if(i==0){

i+=1

}

else{

if(low[$3]<$4)

low[$3] = $4

if(high[$3]>$4 || high[$3]==0)

high[$3] = $4

avg[$3] += $4

cnt[$3] += 1

}

}

END{

for(k in low){

avg[k] = avg[k]/cnt[k]

printf "%s %d %d %.2f ",k, low[k], high[k], avg[k]

}

}' ./Lab03-data.csv

mlib_imagethresh4_fp

mlib_ImageThresh4_Fp(3MLIB)				    mediaLib Library Functions				       mlib_ImageThresh4_Fp(3MLIB)

NAME

       mlib_ImageThresh4_Fp - image thresholding

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_ImageThresh4_Fp(mlib_image *dst, const mlib_image *src,
	    const mlib_d64 *thigh, const mlib_d64 *tlow, const mlib_d64 *ghigh,
	    const mlib_d64 *glow);

DESCRIPTION

       The  mlib_ImageThresh4_Fp()  function compares each pixel in the source image to two threshold values, tlow and thigh. If the pixel is less
       than the lower threshold value, tlow, then the destination pixel is set to the lower output level, glow. If the pixel is greater  than  the
       higher threshold value, thigh, then the destination pixel is set to the higher output level, ghigh. Otherwise, the destination pixel is set
       to the value of the source pixel.

       It uses the following equation:

	 dst[x][y][i] = glow[i]       if src[x][y][i] < tlow[i]
	 dst[x][y][i] = src[x][y][i]  if tlow[i] <= src[x][y][i] <= thigh[i]
	 dst[x][y][i] = ghigh[i]      if src[x][y][i] > thigh[i]

PARAMETERS

       The function takes the following arguments:

       dst	Pointer to destination image.

       src	Pointer to source image.

       thigh	High threshold value. thigh[i] holds the high threshold for channel i.

       tlow	Low threshold value. tlow[i] holds the low threshold for channel i.

       ghigh	High output grayscale level. ghigh[i] holds the high output grayscale level for channel i.

       glow	Low output grayscale level. glow[i] holds the low output grayscale level for channel i.

RETURN VALUES

       The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
