You need to add a conversion step (GB, MB, KB ...) as well as to remove superfluous comas since the dot stand for decimal separator.

Code:
awk -F";" 'tolower($0)!~/parent: line/{k=1024;m=k*k;g=k*m;for(i=10;i<=14;i++) {gsub(",",z,$i);split($i,a," ");s+=a[1]*(a[2]=="GB"?g:a[2]=="MB"?m:a[2]=="KB"?k:1)} print $0 FS "sum=" s/m "[MB]="s/g "[GB]"}' OFS=";" yourfile

Idented properly :

Code:
awk -F";" 'tolower($0)!~/parent: line/{
k=1024;m=k*k;g=k*m;
for(i=10;i<=14;i++) {
        gsub(",",z,$i);split($i,a," ")
        s+=a[1]*(a[2]=="GB"?g:a[2]=="MB"?m:a[2]=="KB"?k:1)
    }
print $0 FS "sum=" s/m "[MB]="s/g "[GB]"
}' OFS=";" yourfile

TOLOWER(3)						   BSD Library Functions Manual 						TOLOWER(3)

NAME
tolower, tolower_l -- upper case to lower case letter conversion LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <ctype.h> int tolower(int c); #include <ctype.h> #include <xlocale.h> int tolower_l(int c, locale_t loc); DESCRIPTION
The tolower() function converts an upper-case letter to the corresponding lower-case letter. The argument must be representable as an unsigned char or the value of EOF. Although the tolower() function uses the current locale, the tolower_l() function may be passed a locale directly. See xlocale(3) for more information. RETURN VALUES
If the argument is an upper-case letter, the tolower() function returns the corresponding lower-case letter if there is one; otherwise, the argument is returned unchanged. COMPATIBILITY
The 4.4BSD extension of accepting arguments outside of the range of the unsigned char type in locales with large character sets is considered obsolete and may not be supported in future releases. The towlower() function should be used instead. SEE ALSO
ctype(3), islower(3), towlower(3), xlocale(3) STANDARDS
The tolower() function conforms to ISO/IEC 9899:1990 (``ISO C90''). BSD
July 17, 2005 BSD
