Working ship dates backwards with Networkdays

[gibbsmachine]

I have a job tracker program that daddylonglegs helped me with a few days ago. I thought I would be able figure this out on my own but failed. I've attached the file to help show what I need. I know the final ship date of a project. Sometimes my projects need to go out for teflon coating. I need Networkdays to give me a TO TEFLON date that is 5 days before the final ship date and factor in weekends and holidays. Thanks in advance.

If you want to add (or subtract) a number of working days to a date then, rather than NETWORKDAYS you can use WORKDAY function, so in F3 try this formula copied down

=IF(D3="Yes",WORKDAY(G3,-A$14,A$17:A$29),"")

Thanks again, that worked great.
