MassHunter Quant Software Qualifier Setup version B.09.00

I'm new to using this version of MassHunter and I am having trouble with getting the qualifier setup. On an older version I have for my other GC, I typically just have to enter in the 3 highest peak m/z values but for this version I need a precursor and product ion. I haven't seen that terminology before so I'm not quite sure what to enter for either of those values. The user manual has not been particularly helpful either. 

Anybody know what is meant by precursor and product ion?
