Simple Animation Question

Hello. I am having a small issue with animations.

I can change the visibility of an object in real time by assigning it to a 'bit' tag, but find that using GETBIT to look at a bit within a word tag does NOT update during real time, only when the screen is 'started'.

I am monitoring the word, and it updates as it should.

Is there any way to 'force' the screen to update (or at least the animation to update) if the monitored tag updates?
