parse_bbcode question

[Xtrm2Matt]

Hi,

An old script my friend made no longer works with vB 3.5.0 (I used it on vB 3.0.3 previously) since a few things were changed. I've managed to fix 99.9% of it, but I'm left with this error and cannot fix it for my life.

The error given is:
Fatal error: Call to undefined function: parse_bbcode() in file.php on line 201

Line 201:
parse_bbcode($row2["pagetext"], $row["forumid"], iif($newpost['disablesmilies'], 0, 1));

Any help would be great. This is the only thing thats stopping the script from working now (commented it out to test)

Thanks in advanced,

Matt
