When a column meets a criteria add 30 days to date field

[CTT53]

I am trying to add days to a date field if another column meets a criteria of Yes.   I am doing this in enterprise guide.    if the column has Yes than add 30 days to the date field column.     Any suggestions?

if column='Yes' then date=date+30;
