title: How is this a mismatched input?
body: <p>So apparently this keeps coming up with the error &quot;Mismatched input ':' expecting ')'. If i break the code up half and cut off the -alertLevel and -impulseLevel parts it works fine, is it because it's so long in the original? Thanks! :)</p>
  <p>bbc = (bbi&gt;0 ? (bbi &gt; alertLevel and bbi &lt; impulseLevel ? col_above :na) : (bbi &gt; impulseLevel ? col_peak : col_null) : (bbi &lt; -alertLevel and bbi &gt; -impulseLevel ? col_fall : na) : (bbi &lt; -impulseLevel ? col_peak : col_null))</p>
