Any simple example of how to use InputField inside Manipulate? I looked an InputField docs and at the following: tutorial/GeneralizedInput but still nothing I tried works. This is what I want to do: I need to ask the user for some parameters (which I know how to use Manipulate to obtain), but I also want the user to enter a free form expression (an equation), and so I need to use InputField, right? but I am unable to do this from inside Manipulate. This is what I tried: attempt 1 ---------- Remove["Global`*"] foo[equation_] := Print["You typed", equation] Manipulate[foo[equation], InputField[Dynamic[equation]]] attempt 2 ---------- Remove["Global`*"] foo[equation_] := Print["You typed", equation] Manipulate[foo[equation], InputField[Dynamic[equation],Hold[Expression]]] and few dozen other attempts. So I give up. If I do not use Dynamic[equation], then how else would I pull out the content of an input field? any help will be appreciated. Nasser
