Bug skipping echo stmnt first time a while loop entered

one more question. I want to skip the first echo statement the first time the loop gets entered

while [ $total_inserted -lt $selling_price ] #keep prompting for more funds until selling price achieved
do

echo "You have inserted a total of ${total_inserted} cents. Please insert $total_remaining more cents"
echo 'Please insert coins (NDQR)'
read coin_inserted

Otherwise the progam will tell user that he entered 0 cents, which is pointless. Any ideas???

add a counter, might not be ideal, but is a cheap solution.

<<before while loop>>
count=0

<<inside while loop>>
test ${count} -ne 0 && \
echo "You have inserted a total of ${total_inserted} cents. Please insert $total_remaining more cents"
(( count = $count + 1 ))
