Classed got closed early on for some reason ???.. fixed now anyways, a '}' was incorrectly placed on line 59

vijayfreaks · August 23, 2007

Hi..

check the open close braces of the code..

Regards,

Vijay

quickstopman · August 24, 2007

ive edited the code check to see where all the brackets are, and it stil says that there is some error on line 37!!!!!

i have absolutly no idea what is wrong

MadTechie · August 25, 2007

add an extra } at the end, whats the error now ?

quickstopman · August 25, 2007

i took it away too...

i think it may be something my version of PHP cause i only have php4 and im not sure how to get php5 do you think that is the problem.

MadTechie · August 25, 2007

NO its not the PHP version problem..

that just proves vijayfreaks, is correct.

remove that last } and remove the contents of on function at a time, until it, runs look, then re-look over that function

Hi..

check the open close braces of the code..

Regards,

Vijay
