If you leave the file path unwired you should get a file dialog prompt, asking you for the file / path. Try disconnecting anything connected to the file path terminal.
Also, you are aware that "Write to spreadsheet.vi" writes a text file that is easily imported into a spreadsheet (like Excel) - right? It does not write it into an xls file. To do this you'll need to use ActiveX components of Excel. It's a bit advanced, but there's a bunch of discussions with sample code on the forum. If you're still having problems, post your code and give some more details. Tim
