I just started using Maple few weeks ago, so i am very new to Maple. I tried to write a program to:

1. read data from excel

2. process the data obtained from different excel sheets to find different possible combinations and calculate costs

3. then to find the minimum cost option

program i wrote is

> with(ExcelTools);
> SHEET1 := Import("analysis.xls", "su1", "A4");
`output redirected...`> print(); # input placeholder
