Hi Joe
Not trying to be a smart ass ,but you need to start over at sq.one.
Just trying to help
Down load the user manual (PDF guide) from Harbor Freight and read it over a time or two.
It will show you how to make the dovetails that will come out right the 1st. time and every time after.
Manual below
http://www.harborfreight.com/cpi/ctaf/manuals.taf?f=form&ItemID=34102
The key is to keep all the stock the same size (thick) MDF is a good one to used for the 1st time because it's a true size.
Besure to mark the stock with A,B,C,D it will help plus put s X on the stock to show the inside of the box.
Plus put the stock edge under the 1st. pin (in the center of the 1st pin) and always use the same router when you do dovetails and set the stop bar for that router.
Most don't put dovetails on the front and back just the front and the sides but the jig will do both and do it very well but it's bit ticky to setup.
Plus you may want to read the link below.
Small error in this type of dovetail jig but you can fix it quick and easy. (see link and snapshot /pictures)
The Error=the finger part of the jig will move just a bit when you clamp the stock down, that's to say it will move to the right or the left and this will off set the joint and with a dovetail joint it must be dead on....
You will not see it until you put the joint together,one will be high or low,by 1/16" the norm.

Just a side NOTE
The box jig(s) that Oak-Park sells are great for what you want to do.
You don't need to use your rubber ruler ,if you want a box that's 11" wide and 20" long that's what you cut the stock for, quick and easy ,then put the slot in for the bottom then but a face plate on the front and your done.
Plus it can be from 1 1/2" to 48" tall unlike the norm. jigs.
