Hello all,
I'm wondering if someone could help me with the following script...It's coming up with a couple errors at the moment.
The errors returned include:
Notice: Undefined index: sce in C:\Sites\Single25\litohin\webroot\chart00.php on line 85
Notice: Undefined variable: PHP_SELF in C:\Sites\Single25\litohin\webroot\chart00.php on line 100
Notice: Undefined variable: doPrint in C:\Sites\Single25\litohin\webroot\chart00.php on line 105
Notice: Undefined index: lang in C:\Sites\Single25\litohin\webroot\chart00.php on line 108
