Well if it is not too late on Monday i can give it a try but you will just accept it if it is too simple

CLS

DIM item(1 TO 20) AS STRING

REM Lets collect user data

INPUT "Enter Customer Names: "; names$ REM is declared implicitely here
INPUT "Enter Transaction date: "; transdate$ REM transdate$ is declared implicitely here
INPUT "Please Enter Number of Item Purchase: "; c
PRINT

REM now lets use array to get other info, using FOR loop
total = 0
FOR i = 1 TO c
PRINT "Enter Details for Item"; i
PRINT
INPUT "Enter Item Name "; item(i)
INPUT "Enter the Unit Price of Item: "; unitPrice(i)
INPUT "Enter the Quantity of Item Bought: "; qty(i)

totalPrice(i) = unitPrice(i) * qty(i) REM Calculating for Item qty price
total = total + totalPrice(i) REM suming up the overall total price
PRINT
NEXT i

REM Printing Summary
CLS
PRINT "SOLA AND CO Business"
PRINT "======================================================="
PRINT " Customer Names: "; UCASE$(names$) REM UCASE is used to convert to Upper Case
PRINT " Transaction Date: "; transdate, , "Date Printed"; DATE$ REM DATE$ print the current date
PRINT " S/N: "
PRINT "======================================================="
PRINT "|   |"; "ITEMS", "UNIT", "QTY", "AMOUNT"
PRINT "======================================================="

FOR i = 1 TO c
PRINT "|"; i; "| "; UCASE$(item(i)), "|"; unitPrice(i), "|"; qty(i), "|"; totalPrice(i), "|"
NEXT i
PRINT "======================================================="
PRINT "GRAND TOTAL: "; total
END

Regards

Thats it so test it am Make the Correction on on it
