Integrate gives wrong answer

Hi, I have a problem on which Integrate misses badly. The code consits

fmin[x_, p_]:=[p(1-(x-a+e)/(2e))^(p-1)]/2e

which is the pdf of the minimum of p draws from a uniform distribution
on [a-e,a+e], and


This produces the output:

\!\(k\ \((\(a +
      e\)\/ni - \(2\ e\)\/\(1 + ni\) + \(a + e\)\/\(k - ni - nj\) +
\(2\ \
e\)\/\(1 - k + ni + nj\))\)\)

which is not symmetric betwenn ni and nj, as it should be.

Any ideas?
