Hi! I'd suggest you to make the fix in Excel. Format the data accordingly and then upload it in Tableau. Best, Ned

The LEFT function calls for a string as it's first parameter, thus you have to ensure that in the 'Data Source' tab, the 'Period' column properties are formatted as a string. I have encountered the error too because it was originally formatted as a value.
