Type Mismatch Error 13 when trying to refresh

[pcrowe45]

Hi.  Is there a way to locate/identify the type mismatch on my gantt excel chart? I tried to refresh my chart and received the Type Mismatch Error 13, and I cannot find the mismatch.

Thanks.

Does the error message have a Debug button? If so, what happens if you click it?

@HansVogelaar Hi Hans. The debug button is greyed out. Thanks.

Could you attach a small sample workbook demonstrating the problem (without sensitive data), or if that is not possible, make it available through OneDrive, Google Drive, Dropbox or similar?
