Fw: Fatal error: Call to undefined function: allerrors() in............

At the beginning of my page I have some code which calls a function I have created, at the bottom of the page is the function, but I keep getting the error Fatal error: Call to undefined function: gotofunction() in ...... no matter what I do. Any info on what's happening is appreciated. example: if ($a == $b) { gotofunction($a, $b); } function gotofunction($a, $b) { a bunch of code; }
