Question : Control visible/not based on value of checkbox- subform (continuous)

Ok, hope this isn't too complicated...

I have a form with several subforms.
I am capturing whether or not a barrier is active with a checkbox (checked = active).
When the end user unchecks the checkbox, I would like two textboxes to appear to capture the date and reason. Otherwise they would not be visible.
On the subform, there are several fields including a checkbox (called active) and two textboxes (among others).

It is a continuous form and would need to be updated as I move through the records on the main form.
So, I would like the two textboxes to remain 'not visible' if the checkbox is checked......
