I have a field named "Price".
I need a javascript that will change the calculate property of this field to be "Value is the sum (+) of the following fields:"

The fields being added would be for example be "A" and "B"

The code below seems close, but sets the property to a "custom calculation script", when I just want the built in sum (+) option for the two fields being added.

this.getField("Price").setAction("Calculate","A,B");

The funciton used to perfrom the actions requested by 'Value is the ___of the following fields" is not what you think it is.

Have you tried the 'AFSimple_Calculate()' function that is used by this GUI?

this.getField("Price").setAction('Caclulate',  "AFSimple_Calculate(\"SUM\", \"A, B\");" );
Of course it is just as easy to use the custom javascript field.
this.getField("Price").setAction('Calculate', "event.value = Number(this.getField(\"A\").value) + Number(this.getField(\"B\").value);" );

I chose your first option for setting the simple calc. At first it didn't work, but then I saw a minor typo on 'calculate' and once I changed that... it works perfectly.

Thank you for your help.
