I have a workbook that prompts me about external data everytime i save
it. There should be no external data. How do I find and remove these
sources?

It may be the result of moving sheets from one workbook to another, I
have attempted to update all formulas to reference only sources in the
current workbook. I just find and replaced [old workbook] with
nothing. I still get the pesky prompt.

thanks
