Back again!

I have another query related to this exact problem and solution you so kindly gave me....

I am now trying to incorporate more source documents to be 'read' by the destination spreadsheet however, as was kind of to be expected, is isn't as simple as copying the last bit of code and duplicating it changing the reference to the third source sheet - this makes the argument appear to have too many sections...

Please help me! I have only just managed to get my head round this nightmare!!
