I'm trying to use NDSolve[...] to numerically solve a differential equation getting an interpolating function which i then need to integrate.

I thought this should be possible using either NIntegrate[], or NIntegrateInterpolatingFunction[].

When both of these are tried however i cant seem to get a numerical answer out, just seem to get back the line that i typed in.

I'm wondering what i might be doing wrong, an example of the sort of thing im trying to do is

solution = NDSolve[...] (this bit works fine)

NIntegrate[solution, {x,1,2}]

or

NIntegrateInterpolatingFunction[solution,{x,1,2}]

I dont get an error, but mathematica doesnt seem to actually do anything

Any ideas would be much appreciated
