D, R, C, & P, Focus on the project Calculus, Mathematics, Tests, Homework, Computers Marketing Computer Drives When it is difficult or very complicated to compute with built-in Excel functions, we can seek help from custom programming. In particular, the Visual Basic language can be used to construct user defined functions in any Excel file. These are accessed via pull-down menus, in the same way that the built-in functions are used. Given the complexity of our cost function, it is desirable to custom program the formula in Visual Basic and attach it to the Excel file. This has been done in Marketing Focus.xls, with the resulting function, COST, being placed in the list of functions under User Defined. Look in the formula bar for Cell E125 in the sheet Functions of Marketing Focus.xls to see how the function is used. To view the Visual Basic code for COST in Office 2007, click on the Developer tab, then on Visual Basic. In earlier versions, click on Tools/Macro/Visual Basic Editor. In the side bar, select VBAProjects (Marketing Focus.xls), double click on Modules, then double click on Module1.  I (material continues) T C Marketing Focus.xls Class Project

However, you will probably find it convenient to use the function COST while working on your team’s project. To transfer the Cost function from Marketing Focus.xls into another Excel file, open both files. Open Module1 (as directed above), click on its icon in the side bar under VBAProject (Marketing Focus.xls) and drag the icon into the VBAProject side bar area of the new file. You can also move modules containing macros or custom functions with export/import. To do this, open the module, click on File/Export File, then select a folder to contain a copy of the module. To attach the module to another Excel file, open the Visual Basic Editor in that file, click on File/Import File, and open the module.  I (material continues) T C Marketing Focus.xls Class Project
