Error:
function formwizard_multiform(&$form_state = NULL) {
Correction:
function formwizard_multiform(&$form_state) {
Description of the Error:
On PHP 4, the above will fail with PHP Parse error: parse error, unexpected '=', expecting ')' in /sites/all/modules/custom/formwizard/formwizard.module on line 34 because PHP 4 does not allow assignment of values to variables passed by reference.
