Days Between and Days on Hold Issue

Content

Hello,

I am trying to calculate the number of days between when a req was first posted and when a job offer was accepted, excluding any time the req was on hold between those two dates.  We can have multiple openings on reqs, so a req could be put on hold after the first job offer was accepted and we wouldn't want to subtract that time out. 

I've come up with this formula, but it is causing multiple rows to pop up with some reqs.  I tried using ForEach with Requistion NO and Candidate ID, but both ways (and together) give me a Multivalue error.
