Multiple fields and want only 1 answer = TRUE or = FALSE

I have created a much larger report, but I am trying to filer the data for something I believe should be very simple. It is proving very difficult and I'm not sure how to get the data out I desire. Below I have listed a sample section from the document.

I am trying to calculate if the data ever shows FALSE then the "PO Correct?" is false. As you see in 300415 the PO is TRUE, therefor the PO was correct. For 300697 the PO was correct 2 times (TRUE) so the PO is correct. On 301220, the PO is TRUE (4) times, but (1) FALSE, therefor the PO was not correct.

PO # PO Correct?
300415 TRUE

300697 TRUE
300697 TRUE

301220 TRUE
301220 FALSE
301220 TRUE
301220 TRUE
301220 TRUE

In this report I dumped data from QuickBooks and am trying to mine if a PO was ever changed in the system, then the PO was not correct from the time it was issued to the time it was received.

Any help anyone could offer on this would be greatly appreciated. I have spent a few hours working on how to figure this out and I am assuming it is a simple solution. I'm not sure if I need to use a formula, macro, pivot chart, exc...
