LOL. I almost posted that when you figure this out you won't believe how simple it is, LOL

Sometimes I am slow but I eventually get there. I like to blame it on the massive amounts of meds that I took for 3 years but I suspect it has more due to age

I am impressed with the simplicity of the design. Very elegant.

Thanks
