After submitting a data input sheet for VNDR_ID_EXCEL CI, I clicked the 'Post Results' button received this error: "Run-time error 1004 Select method of Range class failed".
I have also seen an error after clicking 'Stage for Submission', where the 'Staging and Submission' sheet is created entirely grey with none of the data from the data input sheet.
See the attachments.
