Continuous feed back gauge

Hi

I am quite new to Storyline and this is my first post to the forum, so Hello.

I am having trouble with a project that combines ideas from two examples, the visual feedback gauge & the Job Interview.

What I would like it to do is add to the score on the gauge and move the pointer up each time the user gets a correct answer.

When the question is answered the running total is shown on the gauge but it drops to zero (normal state) when moving to the next slide, and if the user gets it wrong it doesn't show the total at all.

In the Job interview example the triangle stays at the last position (state) as the questions move on and this is what I would like to have happen with the gauge here.

I have attached the file, perhaps someone can see what I have done wrong.

thanks

Cath
