title: pine script : can't use variable as defval of input?
body: <p>I want to use different default value to start base on different ticker</p>
  
  <p>my code: </p>
  
  <pre><code>bars1=iff(myticker=='HSI1!',313,iff(myticker=='YM1!',460,999))
  lower_tf = input(bars1, title='Lower Timeframe to Assess')
  </code></pre>
  
  <p>it gives error:
  Syntax error: Arguments of input function must be of constant type, or 'source' builtin variables; 'defval' is none of them.</p>
