Hello, I am trying to write an "if then" statement to generate an attribute. I would like to generate attribute that  its name is "survived". if att.name.1>=60, then survived="yes" and if att.name.1<60 & att.2="breast" then survived="No". else survived="not mentioned"

    Hi Atefeh,

    You can use the if function of Generate Attributes for this.
