Yes, you can use [math] for that. I am working on a method for user tracking right now and have done something similar. Maybe it is not the easiest, most elegant way, but I could adapt it to your needs and it works...It counts up and down and recognizes an exact match (this can really happen, I know it ;-) You have just to insert date and time of your target in the very first line of code and customize the output section. Be careful with date and time since WebCat takes any value and does not look for wrong input. To test the behavior when a user hits right on the spot, insert [date] and [time] as your deadline within the curly {brackets}.-------------------------------------------------- [math show=f]Deadline={12/31/1998}*24*60*60+{12:00:00}[/math] [math show=f]Current={[date]}*24*60*60+{[time]}[/math][showif [math]Deadline-Current[/math]<0] [math show=f]Difference=Current-Deadline[/math] [math show=f]Hit=-1[/math] [/showif] [showif [math]Deadline-Current[/math]=0] [math show=f]Difference=0[/math] [math show=f]Hit=0[/math] [/showif] [showif [math]Deadline-Current[/math]>0] [math show=f]Difference=Deadline-Current[/math] [math show=f]Hit=1[/math] [/showif][math show=f]D=floor(Difference/60/60/24)[/math] [math show=f]H=floor(Difference/60/60-D*24)[/math] [math show=f]M=floor(Difference/60-D*24*60-H*60)[/math] [math show=f]S=floor(Difference-D*24*60*60-H*60*60-M*60)[/math] [showif [math]Hit[/math]=0] Congratulations - you got it!
