on this 5x8

pins
9 -- 3 -- 4,11 -- 12 -- 6

for the columns

for the rows
13
8
14
10
5
1
7
2

to light up the lower left dot only,  you need to power
2 -- the row and (just 2, lights up the entire row)
to get the bottom left most dot you need to power 3, 4 or 11,
12, and 6.....OK?


now lets say you want the lower left dot and the dot that is
up one row and over one column....???  how do you get only these
two dots, without others ??

this is what I haven't yet been able to do...

when you enable the row above the bottom, the dot directly above the lower
left comes on, only this one...the rest are disabled to isolate the lower
left dot,
and when you try to enable a dot one column over and a row up, you also
get a dot on the bottom row....do you see what I mean??

what easy trick am I missing here....

thanks
