The following JIRA script does not work. I want to know why.

* single select field -> assign auto select

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.issue.fields.CustomField
import com.atlassian.jira.user.util.UserUtil
import com.atlassian.jira.issue.customfields.option.Option
import org.apache.log4j.Level

log.setLevel(Level.DEBUG)

log.debug "Starting postfunction..."
if (issue.isSubTask()) {
log.debug "Issue is subtask, leaving."
return
}

def customFieldManager = ComponentAccessor.getCustomFieldManager()
def approver = customFieldManager.getCustomFieldObject("customfield_xxxxx")
def approverval = (issue?.getCustomFieldValue(approver) as Option)?.value

def userToReassign = issue.getAssignee()
log.debug "Got assignee ${userToReassign}."
UserUtil userUtil = ComponentAccessor.getUserUtil()

switch (approverval) {
case "A":
log.debug "Getting user for A."
userToReassign = userUtil.getUserObject("usera")
break
case "B":
userToReassign = userUtil.getUserObject("userb")
break
case "C":
userToReassign = userUtil.getUserObject("userc")
break
}

log.debug "Setting user to ${userToReassign}."
issue.setAssignee(userToReassign)

* component -> watcher user add

Your going to need to spend time debugging this step by step in your IDE yourself. It's very unlikly someone is going to spend the time doing your job for you on something this big. 

You haven't even given the reason as to why this has failed in the first place
