VBA to extract data from multiple workbooks into another- problem with blank cells

Hi all, I hope someone can help. I have the following code that extracts data from mutliple workbooks and places it in a "summary" workbook. The code works- except if any of the source fields are empty the offset statement does not function as required and the data that should be on the next line appears in the line above. ( if the previous sheet had blank fields)

My thoughts are that if the field is blank then insert a mesage or "-". The most important thing is to keep the datpoints from the same source workbook on the same line. Thanks in advance!!
