Writing data to spreadsheet through references

[Phantom Lord]

Hello,

Ok, this needs to be finished tomorrow so can somebody please help me out? Is it possible to write data coming from my different subVI's, executed sequentially, to the same spreadsheet file? Well, I know that it is possible , but e.g. my waveforms are all connected to the same graph on the main VI through references, so is it possible to connect the reference of every subVI's waveform graph with the value property to build array and then export to spreadsheet? And it would be good if this could be connected to the boolean "write report".

Thanks a lot
