Gavin, I can give you a few suggestions, but it looks like this is an Excel error, and not a LabVIEW issue. msdn.microsoft.com has some excellent resources for the ActiveX controls for Excel.
Are you using this vi as a subVI of a larger program? In the code you gave me, the cells you reference, A2:A4 and C2:C4, appear to be from a new sheet you call temp, and are empty. Maybe XValues only takes a range of cells with values. You=92ll have to look that up. One discrepancy I noticed, which you may already know about, is how you reference both the =93range=94 invoke nodes. You send =93A2:A4=94 and =93C2:C4=94 to cell1, and nothing to cell2. Do you need to send A2 to cell1 and A4 to cell2? When changing this, I still get the same error, but that may be because all those cells are empty. If you do a lot of Word and Excel report generation, you may be interested in the <a href=3Dhttp://sine.ni.com/apps/we/nioc.vp?cid=3D5769&lang=3DUS> LabVIEW Report Generation Toolkit for Microsoft Office</a>. Let me know if nothing here helps, and I=92ll see what else I can find out. Have a nice day! Robert M Applications Engineer National Instruments
