The ultimate result of all values in field 24 will be summed up and output to file say a.txt ,while field 5 and total sum value must be separated by "|"

Say when cat output(a.txt)
0132019832| -1.1

Need help...!

Code:

awk 'BEGIN{FS="|"}
{
 a[$5]=a[$5]+$24
}
END {
     for (i in a) print a[i]"|"i > "outfile"
}
' "file"
