Hi Imtiaz,
Thanks for that - the modifications you made give me the result that I wanted.
I also found another way to do it which I will probably end up using when I implement my project "for real" (this was a bit of an experiment).
In the NI example finder there is an example called "Run Macro on Word Table.vi" which I could adapt for my purposes. I think this method would clear up my block diagram a lot by just having a couple of blocks for importing the data into Word, and then the module code for a Macro that I record in Word that can do all the complex formatting in one go.
Thanks again for your assistance,
Ian
