problem with created form

problem with created form

Hi! I am using the webtool enabled by zoho.creator for academic research purpose, and it worked very well until now... Three days ago, I copied a pre-existing form, and worked to create a new form with some differences. But it does not work! I don't know what it is happening... the permalink is:
http://creator.zoho.com/hamagust/parq_base_tec/form-perma/Parq_Base_Tec_Form/


Help me, please! this link is already available for respondants...

best regards,

Tomoe Gusberti
