Error when activating plugin

Hi,

I have just tried to activate the plugin but I am getting an error. Please see below:

Plugin could not be activated because it triggered a fatal error.

Parse error: syntax error, unexpected T_STRING in /home/PROTECTED/public_html/PROTECTED.com/wp-content/plugins/anspress-question-answer/includes/process-form.php on line 143

Please could you tell me how to fix this?
