Cash Register help

[osmanrulz]

Erm iv written a a small cash register program, thats finds out the name of a restuarant and accepts the price for a meal and prints the bill. What i have been instructed is.. if the meal if over $5.00, i shud display a 7% sales tax. The program is assigned to work if several meals are entered for one bill, which i have trouble modifying, It should also work for several customers (different bills). Now I only have been close to the midterm of my programming class and all i know is loops and selection, if statements and end statements and all the basic stuff. How can i make this program work for several meals entered for one bill, and then calculating that with a salestax or without it. This is what I have completed so far.

code:

%Osman Ahmad %Finds the Total Cost of Your meal and adds a 7% tax if greater than 5 dollars %November 21/06 var cost, total, cash, salestax : real var restuarantName : string put "*********************************************" loop put "What is the Restuarant Name?" get restuarantName : * put "| Welcome to ", restuarantName put "************************************************" put "Please enter the amount of your meal: " .. get cost put "*********************************************************" if cost <= 5.00 then    total := cost        put "You have no sales tax, your meal does not exceed $5.00!"        put "Salestax (0%): $0.00"        put "Tax Total (You do not have a tax): $0.00"         put "Grand Total is: $", total         put "*****************************************************"         put "Please enter your amount of cash (Bill or overall change): $" ..         get cash         cash := total - cash         put "***************************************************"         total := cost + salestax         cash := total - cash         if total >= cash then             put " Please give right amound of cash: $", cash - total         elsif cash >= total then             put "Your change is: $", cash - total         end if         put "*************************************************"         put "Thanks for Purchasing at " , restuarantName         put "***********************************************"     elsif cost >= 5 then     salestax := cost * .07     put "You have a sales tax of 7%, your meal exceeds $5.00!"     put "Salestax (7%): $", salestax     put "Tax Total: $", salestax     total := cost + salestax     put "Grand Total is: $", total     put "****************************************"     put "Please enter your amount of cash (Bill or overall change): $" ..     get cash     cash := total - cash     put "************************************************"     total := cost + salestax     cash := total - cash     if total >= cash then         put  Please give right amound of cash: $", cash - total     elsif cash >= total then         put "Your change is: $", cash - total         put   "Next Customer"       put "Thanks for Purchasing at " , restuarantName         put "*******************************************" end if end if end loop

oh and sorry I didnt post this in the first message, I also need to round the total to 2 decimal places, and i forgot how to do that , so if I could have help with that too. Thanks.

Well Turing has a nifty round function that rounds off the decimals.

code:

put round (5.7)

You want it to round to two decimal places so somehow you are going to have to move the decimal, round the number, and move the decimal back.

yess thanks so much, so it should me something like this? , I still have this annoying error that keeps popping up when I enter an amound for my meal i.e 4.22 and I enter say 5.22 for my Bill, it gives me a no variable error. Also I would like to know how I can make it calculate and input/output multiple meals, using for statements, but I seem to be having trouble doing that. It should be something like this.
put "How many meals would you like to order.."
get numMeals
put "What is the Price of meal 1?"
put "What is the Price of meal 2?" ... etc
