Hi @Lauren_healey. You have to use the SketchedSymbol.GetResultText method. That method wants you to specify the exact Inventor.TextBox object containing the 'prompted entry', then it returns its current 'result text'. There is also the similar SketchedSymbol.SetPromptResultText, which works in a similar way. You can find the right TextBox object by iterating through them, and checking their TextBox.Text property value, which will usually contain something like "<MyPromptName>". Then capture that TextBox to a variable that was declared before the iteration of TextBoxes, so that you can use it after that block of code for the method, or just use that method within the loop, at the point where it is found.
