integration of a timer to php scripts.

[joyce]

hi all, i'm new to javascript and hope to get some advice here.

i've dl a timer, which is generated by javascript. this timer is something like a count down...and this scripts works fine.

i want to integrate this timer with a php script. when i combine them, i have errors. i dono what to do because i dono much of javascript.

this is the url of the page that i want to add the timer:

http://www.certifyexpress.com/exam/microsoft/index1.php

select an exam and click the button 'Take the quiz'. that is the page where the errors occcurs.

pls help. thank you.

[weirdbeardmt]

Hard to say anything much because the source code doesn't have the offending Javascript in it.

Can you post both the code of the page which has the timer running and the code of the timer script.

[joyce]

i fixed the errors already. but another problem occured. which is..in this url,

the url:

http://www.certifyexpress.com/exam/microsoft/index1.php

i choose one exam and i click 'take the quiz'..i will go back to the same page. it suppose to go the other page if i didnt' add the timer.

this is the code: (it's kind of long)
