Solving a differential equation I found that its solution was analytic, and I stored it as an expression from the default rule output of the `DSolve[]`

function:

`soleq2 = y[x] /. soleq2[[1, 1]]`

Which has output:

`Sqrt[x] BesselJ[Sqrt[13]/2, x] C[1] + Sqrt[x] BesselY[Sqrt[13]/2, x] C[2]`

I then plotted this:

`Manipulate[Plot[soleq2, {x, 0, 10}], {C[1], 0, 10}, {C[2], 0, 10}]`

but the plot does not show anything, only the sliders for the modulation of `C[1]`

and `C[2]`

. I tried substituting these constants with other letters thinking their format might interfere with the kernel, but to no avail.
