Total = BarChart[{1, 2, 3, 4, 5, 6, 7, 8, 9, 10}, {a, b, c, d, e, f, g, h, i, j}][br][br]The first list is the value of the bar. The second list is the height of the bar.

Caveat: entering the command above as is did have some problems with the letter e...taken as a constant...suggest using {a1, b1, c1, d1, e1, f1, g1, h1, i1, j1} to prevent problem...and have GG create the sliders.
