Each of the Hot Potatoes modules acts differently, but basically, the score is only reported once Hot Potatoes has decided that the activity has been completed. No intermediate scores are sent to the database.
Please download the revised hotpot.php found in the "Fix for pix" thread and see if that gives you any better results. If not, please send me your original .htm file. I also need to know what system you are using and what kind of server you are using (Linix/Win).
I've never checked to see if the action after a warning message is appropriate or not. I'll take a look at that.
