Expression editor & function expressions

in Help
I would like to know how and where I can access the Expression Editor in Rapidminer. 
In addition, I struggle to put Square function in Generate Attribute. I have created a Total, and I would like to add a Total Square in Generate Attribute. But when I type square (Total) in function expressions, it gives me an erroneous amount. 
Could you help me out?

    In Generate Attribute operator, when you create a new attribute you will see a tiny calculator to the right of the function expression field, just click it and bingo!

    Also, if you do not have an attribute "Total" it will not calculate it. You may have done so. If not then If you want to get a total of an attribute, you need to use an "Aggregate" operator to calculate some column statistics, e.g. the sum of the column. Then you can use it in your calculations within your "Generate Attribute" expressions.
