It sort of works but  doesn't.

can I get some help here?

Currently I'm sick and my brain doesn't work well but you can try this:

I got this working.

Func Angle($tX, $tY, $cX, $cY)
    $mx = $tX - $cX
    $my = $cY - $tY
    $angle = ATan($my / $mx) * $180_div_pi
    If $mx < 0 Then
        $angle = 180 + $angle
    ElseIf $mx >= 0 And $my < 0 Then
        $angle = 360 + $angle
    EndIf
    Return Int($angle)
EndFunc
