Hello Андрей,

Do you wish to change the text on the 'Send' button?

This can be done in Step 1 - General Settings - Basic tab...  click on the icon to the far right of the 'Content Language' field...  the Language Content Management screen will open.  Scroll down the list of variables until you find 'form_submit'  -  if you then place your cursor on the right-hand column you will be able to edit the text as you wish.

Be sure to exit the screen by clicking the 'Close' button  -  if you exit by clicking the red cross in the top right hand corner then your changes will not be saved.

Kind regards,

Paul
