clock and echo problem

[jotapan]

Hi to all,

I have been trying for some time to add a countdown clock display in my 
programs that informs the participant on how long he(she) still has to 
respond in a given task (e.g., during a slide presentation). I have 
extensivelly looked in the forums for this information. I found a specific 
post where 2 suggestions are presented (Displaying a countdown timer for 
participants, originally posted on/ I was able to work around the script 
/). I could not get the first suggestion to work... I was able to  work 
around the script provided in the e-prime countdown sample, although it is 
not perfect; the countdown example deals with seconds and I need minutes. 
So instead of having "lnCountTime = (lnEndTime - Clock.Read) / 1000", I 
have lnCountTime = (lnEndTime - Clock.Read) / 60000. Not perfect but ok.

However, I get an echo problem with this. I want the participant to be able 
to see all the responses he(she) is providing throught the task and them 
have them disappear when the program moves to the next slide. To get the 
countdown clock to work I have to set the duration of the slide to 0. If I 
set the "time limit" to "same as duration" it assumes the 0 duration and so 
the echo is not displayed anymore... is there a way to add in the inline a 
command to finish the echo when the time is up?  

Simply displaying a clock on the slide for the entire slide presentation 
would work for me as well (instead of the countdown clock) and could help 
solve the echo problem. Is there a simple way to get a clock being 
displayed on a slide?

I really appreciate all the help I can get on this.

Jotapan
