Getting NaN with Javascript variable

blue72TAAug 12 2011 — edited Aug 12 2011

Hello All,

I'm learning javascript and I'm having a problem. I can't seem to use a variable correctly in javascript. The function below shows the problem. When I use the vRow variable my value gets set, however when I try to use link_line variable I get NaN in my tabular field (f37).

Can anyone spot the problem here? I've tried everything including parseInt, parseFloat conversions but I can't figure out what's wrong.

Thanks for your help!

<script>
function f_ValidateLinkLine(pThis) {
    
   // The row in the table
 var vRow = pThis.id.substr(pThis.id.indexOf('_')+1);

  // A value entered by user in tabular form on this row
 var link_line = parseInt(html_GetElement('f20_'+vRow).value);
  
     // Set the value for f37
 
    // This works!
    html_GetElement('f37_'+vRow).value = parseFloat(html_GetElement('f01_'+vRow).value);

    // This puts NaN in my field! Why?
    html_GetElement('f37_'+vRow).value = parseFloat(html_GetElement('f01_'+link_line).value);
 
    } // End ValidateLinkLine

</script>
