The data above is an example of my data.
This code is almost working how I want it to, but not yet. INTCK is semi-working, and I'm not sure how to completely get it to work (it will say 'Y' for NOV 2011 and 'Y' for JULY 2013, but 'N' for JUNE 2012. Is there a way to fix this? I also want this to return 'Y' for types 3 and 4 if they're 1 day between each other (January 1st and 2nd) and it isn't doing this. How would I fix these?
