Client script syntax question

Client script syntax question

Hi, 

I don´t know why this sytax is incorrect. 

/**

 * log("sample logging statement") --> can be used to print any data in the browser console.

 * ZDK module can be used for customising the UI and other functionalities.

 * return false to prevent <SAVE> action

**/

var criterio = ZDK.Page.getField('Data_Processing_Basis').getValue();

var boton = ZDK.Page.getButton('convert')

if (criterio != "Consent - Obtained")

{

boton.disable();

}
