Hi, myfun = x^2 + 3 t x; t = 1; Plot[myfun, {x, 0, 2}] Clear[t] Manipulate[ Evaluate[myfun /. {x -> \[ScriptX], t -> \[Tau]}], {\[ScriptX], 1, 2}, {{\[Tau], 1}, 0, 10}] Manipulate[ Plot[Evaluate[myfun /. {x -> \[ScriptX], t -> \[Tau]}], {\[ScriptX], 1, 2}], {{\[Tau], 1}, 0, 10}] ? And a x in Manipulate[] is not a x as to see from Manipulate[{Hold[x], x}, {x, 0, 1}] Regards Jens mgoic wrote: > Hi everyone, > > I am having problems when trying to plot an expression in a Dynamic > model using manipulate tool.
