VBA Headers and Array

Hello Everyone,

I just joined this message board after having very little success in altering my VBA code. I have a data file and when I run the VBA code, it only works partly. Currently when I run the code, it will create new month headers, but only for a 12 month period and it is based off the current date on the computer. I need this to go to whatever specified date range I choose and I especially need it to go for more than 12 months. I am also having some issues because when my code runs, it is not running back far enough and there are gaps in the analysis that it does. For instance, after changing the time on my computer to 2009, project A and B's data stops in June 2009, even though the define phase is occuring before that. I have attached the code and I am looking for any help. Thank you very much and I hope someone can help me. Please let me know of any questions.
