Hello-- I'm trying to figure out how to properly display a matrix/grid question based on a number entered in a previous question.

Specifically, the first question is: How many children do you have? (enter number); based on the number entered, the next question should display a grid with a row for each child and the option to select the age and gender of each. For example, respondent A answers 2 children, they will then see a grid for 2 children, respondent B answers 5, they will see a grid for 5 children, etc.
