Weird Messages upon install upgrade

Hi All, Ive just run into some bizarre problem. I upgraded to a more recent version of PHP and have run into some bizarre problem. We were running version 4.0bsomething on a FreeBSD box with Apache and ive just installed 4.0.3pl1 and ive managed to get pretty much everything working, except for a couple of sites ive designed im coming up with some weird errors on functions which otherwise have been working fine. They only started appearing when I upgraded the version of PHP. Here is the errors im getting when I call the page..... --------------------------------------- Warning: Missing argument 2 for stripe() in /location/to/included/file.php on line 257 Warning: Missing argument 3 for stripe() in /location/to/included/file.php on line 257 --------------------------------------- Now, line 257 looks like this (ive included the rest of the function, but the first line is line 257) --------------------------------------- function stripe($title,$bgcolor,$fgcolor) { global $darkcolor, $lightcolor; if (!$bgcolor && !$fgcolor) { $bgcolor="$darkcolor"; $fgcolor="$lightcolor"; } ?> <table BORDER=0 WIDTH="100%" BGCOLOR=<?echo($bgcolor)?>><tr><td> <b><font color=<?echo($fgcolor)?> size=+1 FACE="helvetica,arial">&nbsp; <? echo($title) ?></font></b></td></tr></table> <? } ----------------------------------------- This isnt the only function which is causing me problems but this is the smallest one for an example. Is there something I havent compiled into PHP properly? or can there be something else? Any help on this would be greatly appreciated. Thanks Chris
