salary requirement in appendix5 - mismatch in documents

[mmg]

I submitted a PBS- Tier2 application recently. In Appendix 5 for claiming salary requirement, I have mentioned offer letter of sponsor as document attached. But, I did not attach that document while giving it at VFS, India. I understood recently that COS will serve as salary requirement and that is sufficient for that purpose. But, I am in a paranoid if my VISA is refused just because I mentioned a document as supporting document and did not enclose that. Will UKBA take my COS in consideration or asks for my offer letter or simply refuses my application just saying missing documents?

take it easy..
UKBA is going to look up for COS detail on the system and against the COS, ur employer would have already mentioned all your details including salary. hence, there is nothing to worry about.
