EXCEL CHANGE

Strong excel knowledge required to correct new input process in existing excel scoring application. The application (pastperform 20) was created 2 years ago as a conversion of an existing [login to view URL] application to excel. The application was originally created to buy, download, unzip and automatically score a data file sold at a thoroughbred racing website. That was the original plan for this app to be used by horseplayers with little or no computer skills. This automatic scoring is no longer needed. The need now is for a file Open Window for the user to open his selected unzipped data file,whereupon the application then scores the data of that file. There are 3 scoring columns on pastperform 20 identified as XL,D6,D12. These 3 scores will remain, the only change will be the Open window for the user to select and open the chosen data file for scoring. The automatic default scoring will not be in place, only the file that the user selects. I have chosen the existing application (pastperform [login to view URL]) along with a data file "crc1121.eg" which is an unzipped data file.I am having difficulty with Microsoft error messages, with a computer that has xp professional operating system. If you can correct this application with Excel, and eliminated the error messages while inserting the Open File Window, you have accomplished this project.
