Suppress the 'answer' box (for extensions)

[Ruth Hand]

Has anyone worked out a way to suppress the answer input box when using GeoGebra (or other extension)?  I don't want the student to see the way GeoGebra sends the answer to Numbas as it gives the game away!

The 'extension' part type exists for exactly this purpose - it has no input box. This question shows how to do it: https://numbas.mathcentre.ac.uk/question/68262/mark-a-part-as-correct-if-the-student-moves-a-point-to-the-right-position/

Thanks Christian.  I was using the extension part for things similar to your example, but have got into a mess when the answer is an equation, rather than a point.

I can't seem to get it marked correctly with an extension part type, but can when it autofills a maths expression box.  I assume I am doing something wrong in my 'correctif' line, I will have another look today.

Thanks again
