Creating a simple chart

Parameters prompt the user of a report to enter information. Think of a parameter as a question that the user needs to answer before the report is generated. The information users enter, or the way they respond, determines what appears in the report. For example, in a report used by salespeople, there might be a parameter that asks the user to choose a region. The report would return the results for the specific region, instead of returning the results for all of the regions.

By using parameter fields in formulas, selection formulas, and in the report itself, you can create a single report that you can modify whenever your needs change. Parameter fields can also be used in sub reports.
