CAPTCHA Validation

Use "CAPTCHA validation" plugin to ensure your survey or form is submitted by real respondents instead of computer bots. Insert new question of the Single Line text with pre-format options type at the beginning of your survey or form and ask respondents to enter code for validation. You can also reference to the existing question. Then go to the plugin's edit page and reference to this question using the following parameter:

1. *Question Reference - Enter reference to a new question where you ask respondents for the validation code. Use Qx.Ay format, where:
   x - question number;
   y - answer choice number.

Please note, that this plugin also works with question and answer identifiers, so you can use them instead of question and answer numbers in plugin parameters.
