Hello there ^_^

I need a help or suggestion in the attached example. I want to assign a formula to one field in which the result should insert in the field.


In the example:

the user should insert number or nothing in the following fields: Grade1, Grade2, Grade3



Grades will accept Null and numbers





The result should appears in the field: Total



The formula should be like ((Grade1)+(Grade2)+(Grade3))


In case that i don't have the grades I can fill the total field manually!!


I will appreciate any help or suggestion



Many thanks in advance J
