Reset numeric entries with "Try Again"
Hello, I have a quiz question that looks at a numeric entry field that in reality, is the sum of two other numeric entry fields (fields 1 and 2, respectively). The two other entry fields are assigned variables "Inc_Angle1" and "Inc_Angle2", and they are summed to variable "Sum_Inc_Angle". The numeric field has as a reference "Sum_Inc_Angle". Eventually it will be a hidden field.
OK, so far so good. It's working. However, the user gets 3 chances to get the two entries (e.g. the sum of the entries) correct. I have a trigger that resets "Sum_Inc_Angle" to zero when "Try Again" is pressed. I want to also set the other numeric fields to <null> when the "Try Again" button is pressed (e.g. like when slide is initially entered). I added the trigger to "jump to slide" (the same slide) when "Try Again" is pressed, and the slide set to "reset to initial state" when revisiting. However, the two numeric entry fields are not emptied, but retain their previous values. I can add other triggers to reset the initial variables to zero which kind of gets me where I want to go, but not exactly.
Is it possible to do what I want?
