How to verify that the variable "does not contain" a value?

Question

Hi
I am using CP 7.0.1.237.
We want to use Text Area widget for a custom quiz and verify an answer. While we figured out how to verify the existence of certain keywords, we are not able to figure out how to verify that the content should NOT contain certain keywords. For example, we want to ensure that the text entered in this widget should not contain "Transformation" and "Non-compliant".
Is this possible at all?
Thanks

Here's what the solution might look like in JavaScript.  This would be for SWF output and aimed at Cp 7.  For Cp 8, this would still work for SWF output, but you'd probably want to take advantage of the new unified JS API that gets and sets Cp variables for both SWF and HTML5 output.  You can read more about that here:  Common JS interface
//Get the text area value from Captivate (SWF output Only)
var cpTextAreaValue = document.Captivate.cpEIGetValue('m_VarHandle.v_TextArea);
//convert the value to lower case to properly compare
cpTextAreaValue = cpTextAreaValue.toLowerCase();
//Check if text area value contains the words "transformation" or "non-compliant"
if(cpTextAreaValue.indexof('organizational') > -1 && cpTextAreaValue.indexof('behavioral ') > -1 && cpTextAreaValue.indexof('managerial') > -1 && cpTextAreaValue.indexof('transformation') < 0 && cpTextAreaValue.indexof('non-compliant') < 0){
  //the text area has the correct answer so increment varScore
  //get the current score from Captivate
  var score = document.Captivate.cpEIGetValue('m_VarHandle.varScore');
  //increment score by 1
  score++;
  //set score in Captivate
  document.Captivate.cpEISetValue('m_VarHandle.varScore', score);
} else {
  //the text area does not have the correct answer so show message to user inside of Captivate
  document.Captivate.cpEISetValue('m_VarHandle.v_message', 'Answer is not correct');
This JS has not been tested.  Note that the "does not contain" operator is done using the "indexof" operator in JS.
