Stock Reconciliation Not Uploading - No error message

I wanted to amend the stock quantity figures and tried the stock reconciliation procedure with no success. I don’t get an error message it just doesn’t upload.

Again I tried this with just one item and made sure the name and warehouse were correct. I also checked that I had ticked Stock Item Yes but again it did not upload but no error message.

Not sure if I am doing something basic that is wrong. New to this apologies if this has been addressed earlier but I cannot find it.

Thanks.

I seems the Stock Quantity Column needs a zero if zero stock and I had blanks. Now uploading!
