Hi, all
    I want to findminimum of a function f[x,a[0]]=x^2+a[0]*x over 
{x,0,1}, where a[0] is the solution of a differential equation, say 
{a'[z] = x*z, a[1]==1}. The code is
like,

FindMinimum[x^2+a[0]*x/.NDSolve[{a'[z]==x*z,a[1]==1},a,{z,0,1}],{x,0,1}]

now the problem is that I can run this code in mathematica 4.2, but 
can't in mathematica 5.0, do anybody know what is the problem? or what 
should I modify to do this FindMinimum in mathematica 5.0?

thanks,

Jiang
