Question Acces InputField from Script

Hi there,
I am trying to acces the text from an InputField which is a child.
--- Hirachy --------
- InputCanvas
-- Image <Image>
-- MathInput <InputField>
-- Math <Text>
----------------------

I can acces the Math<Text> Propertie with the following:

Code (CSharp):

1.  
2. GameObject InputCanvas;
3. InputCanvas = GameObject.Find("InputCanvas");
4.  
5. Transform textTr = InputCanvas.transform.Find("Math");
6. Text mathText = textTr.GetComponent<Text>();
7. mathText.text = "This is my Text";
8.  

But so far I have had no luck accesing the text which is in the InputFields Text property.

Any Help would be greatly appriciated!

Best wishes
/Thomas
