match up formula

hi, this is my first topic and im not very clued up on forums, just though it would be a good place for some urgent help, ok, this is my question, as per my file i want to match up data from column D with data from column B and if found match, copy it to column C to the same raw as the match found, i hope someone out there can give me some help its very much appreciated.

thanks in advance
