Excel 2007 :: Chart That Reads Results Of Multiple Dropdown Boxes?

Using Excel 2007

I have six colums (Date; Skill; ST Hrs; OT hrs: Area; Type). I copied and pasted below a small portion of info from the spreadsheet. I know when I copy and paste into a post the information under the headers don't line up exactly...it appears offset, so basically "Date" is of course the date you see..."Skill"'s columns has the first item as nb-mech b..."ST Hrs" first item will be 0.00..."OT Hrs" will be 1.50...."Area"'s first item is "Log FM NO"....and "Type"'s first item is MX07

And there are 17,000 rows of this info and forever growing...a lot of repeated items in each column such as you can see "blaster" has multiple entries on 4/1/2012.

What I am attempting to do which I have not firgured out yet (i have tried array formulas but they bog down the pc forver and couldn't figure out exactly how to make it give me the results I needed...and I also tried sumproducts but that didnt get me what I wanted....and it is being requested of me to NOT make a pivot table but a chart.

What I am trying to create is is the following:

1 - cells to plug in a date range for example cell A1 I plug 4/1/2012 and cell A2 plug 4/30/2012
2 - drop down boxes for columns Skill; Area: Type, which show only unique records in each column

Once I have that, I could then filter all 3 itmes and have only items show in the date ranges I picked and present ONLY the SUMS of columns ST Hrs and OT hrs.

Once the SUMS show up, I can then have cells off to the side that will give a percent break down of what percent of the total hours (for the chose criteria) are ST Hrs and what percent of the total are OT Hrs....and this percentage break down will show up in a Bar Chart, per day chosen in my date ranges....I'm thinking one simple stacked bar per day in the chart.

So say, based on the info below, I wanted to see the total ST Hrs and OT Hrs from 4-1-12 to 4-2-12 for a nb-blaster in LOG FM NO and type MX06.....my result would be 0.00 ST Hrs...23 OT Hrs.....and my bar chart would be one simple bar peaked out at 23 on day 4-1-12.....and within the bar it would be 0.00% ST Hrs and 100% OT Hrs and maybe the total hours for each showing also..don't need that but it may be useful.. ..and no bar for 4-2-12 (because the criteria picked had no hours for 4-2-12)

I have been messign witht is all week and just can't nail it.. I do remember a while ago I would have been able to load the spreadsheet into the post and people could see it in excel...is that option to do that no longer on this site?
