How I can set a field value to be added automatically based on the value of three other fields, one of which is the autoincrement field (field1 = 2, field2 = 5 and field3 = 1 then myfield value = 251, all types of these fields are an integer

You may simply use jQuery code to combine all those 3 fields into one value, and put it in “Startup Script” of “Add Page” and/or “Edit Page”. Just Google “jquery combine three input values” for more info and examples.

You need to trigger based on keydown or change event of the textbox control. Google is your friend.
