Filled Plot

Hi folks,

I have been having problems with using Filled Plot. Essentially I am 
trying to code up a one dimensional FEM code using linear interpolating 
functions, but I would like to fill my plots where each element 
interacts and FilledPlot does not seem to do its job. Any help or work 
arounds??

<< Graphics`FilledPlot`
n = 4
h = N[1/n]
phi1[x_] = Table[Piecewise[{{1/h*(x - (i - 1)*h), h*(i - 1) < x <
  h*i}, {-1/h*(x - (i + 1)*h), h*
          i < x < h*(i + 1)}, {1, x == i*h}}], {i, 0, 1/
              h, 1}] // PiecewiseExpand // Simplify
Plot[{phi1[x][[1]], phi1[x][[2]], phi1[x][[3]]}, {x, 0, 1}]
FilledPlot[{phi1[x][[1]], phi1[x][[2]], phi1[x][[3]]}, {x, 0, 1}]

Thanks

Pratik
