can you have a number as the ID in a vba collection
You also have a number of worksheet reports that have lists of student IDs. For each of these worksheets you need to print the mark for each student. You could do this by adding the 10,000 students to a collection using their student id as they key. The items do not have to be of the same type but they normally are. 2  The VBA Sheets collection can contain both worksheets and chart sheets. 3  A collection makes it easy to perform the same task on multiple items e.g. print all the values.
