## Question:problem with slider for odeplot

Maple

Hello,

After we solved two equations we want to plot them with two sliders. I am trying to have two sliders for k and mu. I followed what this link suggested:

http://www.mapleprimes.com/questions/119732-How-To-Code-Sliders-To-Make-It-Easy

But I get this warning:

`Warning, `p1` is implicitly declared local to procedure `myplot``
` `
`This is Maple code:`
`> restart;> with(plots);> with(DEtools);> eq1 := diff(x(t), t) = v(t); eq2 := diff(v(t), t) = -k*x(t)*(1-1/sqrt(x(t)^2+.25^2))-mu;> inti[1] := x(0) = .12; inti[2] := v(0) = 10;> sol := dsolve({eq1, eq2, inti[1], inti[2]}, {v(t), x(t)}, numeric, parameters = [k, mu]);> myplot := proc () `
`local k, mu; `
`k := DocumentTools:-GetProperty('kSlider', 'value'); `
`mu := DocumentTools:-GetProperty('muSlider', 'value'); `
`p1 := odeplot(sol, [t, x(t)], t = 0 .. 25, colour = red); `
`plots:-display([p1], scaling = constrained) `
`end proc;`
` `

Is this because I am using odeplot to plot the solution?

Any suggestion?

Thank you
