Pasting from Excel into Time and Expense

I am trying to streamline entry of Time and Expense for our Service engineers, however,I get the following error
sheet attached
Time and Expense Entry sheet.xlsx (9.3 KB)
Really need to update the process, so any help would be greatly appreciated.

After looking at the attached excel files, I can immediately see the problem. You have some rogue data

Dear @AVWebb,

I have checked the attached file and identified that ASM (Job Assembly) column value is missing. Could you please enter the value and try to upload.
