Macro to insert data in specific cell based on criteria

I'm re-posting this in the hope that someone can help.

In the example enclosed I'd like to add some code to a command button on Sheet 2 so that the data on Sheet 1 cell M27 is entered in to cell C12 on Sheet 2 because of the criteria set out in Sheet 1 cells H2 (Week) and M2 (Identifier) - the data is inserted in to the relevant point on the matrix in Sheet 2.

Any help appreciated.

Thanks Steve
