Compatibility issues with .xlsm file made in Excel before 2007

[Jose_Valerio]

One or more functions in this workbook are not available in versions prior to Excel 2007. When recalculated in earlier versions, these functions will return a #NAME? error instead of their current results.

Current Excel is 2016.

Any ideas?

Thanks

Jose

Are you perhaps using the wrong file format to save to? Like "Excel 97-2003 workbook (*.xls)"?
