how would you calculate percentage by per line? Given a column of 16 lines, grab each line and divide it by the sum of the entire column and multiply by 100?

Hello,
I am trying to compute the percentage in a script as shown below:
PerCover=`echo "scale=2 ; 100 \* ($InputCover/$Total)" | bc`
However the PerCover value is blank/null. What do I need to do differently?
Thanks for your input!

LEARN ABOUT BSD
ddd
DDD(1L)DDD(1L)NAME
ddd - double-speed data dumper
SYNOPSIS
ddd [option=value] ...
DESCRIPTION
Ddd works almost the same way as dd(1), but it has a much better throughput, especially when used with slow i/o-devices, such as tape
drives. The improvement is achieved mainly by dividing the copying process into two processes, one of which reads while the other one
writes and vice versa. Also all code conversion capabilities are omitted. There is no additional overhead copying data between various
conversion buffers.
Ddd was inspired by the vast difference in speed between BSD4.2 and BSD4.3 dumps - in BSD4.3 dump(8) uses alternating processes to write to
raw magnetic tape, thus keeping the tape continuously in motion. I wanted to get the same improvement to remote dumps, so this filter was
needed. Directing all physical I/O through ddd usually increases the throughput of any pipeline of unix commands (if you have enough MIPS
and RAM to handle two extra processes).
OPTIONS
Ddd uses options if, of, ibs and obs exactly as dd(1). Option bs can also be used to specify ibs and obs at once. One option differs
slightly in meaning: cbs can be used to specify the size of the internal buffer. Input and output processes will swap duties when cbs
bytes have been transferred. Default values for all sizes are 512 bytes. As with dd(1), letters k (kilobyte), b (block) or w (word) can
be appended to size values. Other options are not provided.
HINTS
For best performance, block sizes should be rather large. For magnetic tape, I use obs=100b and cbs=500b or so. Large block sizes (~100b)
are also effective for network connections. However, cbs should be small enough for all the data to fit in core, since page faults add
overhead.
