How can I get my bash script to work?

#!/bin/bash

total="0"
count="0"
#FILE="$1" This is the easier way
for FILE in $*
do
    # Start processing all processable files
    while read line
    do
        if [[ "$line" =~ ^Total ]];
        then
            tmp=$(echo $line | cut -d':' -f2)
            count=$(expr $count + 1)
            total=$(expr $total + $tmp)
        fi
    done < $FILE
done
echo "The Total Is: $total"
echo "$FILE"

while [ $1 != "" ]
  do ....
done

while [ "$1" != "" ]; do
    # Code here

    # Next argument
    shift
done

grep '^Total:' "$@" |
cut -d: -f2 |
awk '{sum += $1}
     END { print sum }'

grep "^Total:" "$@" |
awk -F: '{sum += $2}
         END { print sum }'

awk -F: '$1 ~ /^Total/ { sum += $2 }
         END { print sum }' "$@"

perl -na -F: -e '$sum += $F[1] if m/^Total:/; END { print $sum; }' "$@"

while [ $# -gt 0 ]
do
     ...process $1...
     shift
done

#!/bin/sh

process() {
    echo "doing something with $1"
}

for i in "$@" # Note use of "$@" to not break on filenames with whitespace
do
    process "$i"
done

while [ "$1" != "" ]; do
    # Code here

    # Next argument
    shift
done
