Replicate ratingScale acceptResponse function

Builder
1

I have two rating scales in a routine, and I need to force the participant to respond to both before moving forward. In custom code I tried

if not len(myscale.getHistory) > 1:
    continueroutine=True

but that makes the scales behave weirdly. I tried making my own button with the code:

    myscale.acceptResponse("")

instead and that records the scale position but not the RT!
What am I missing, please! How do I replicate the function of the scale’s accept button using my own button?
