Script cannot recognize custom fields

This question perhaps has been asked many times but I could not locate one in the forum.
I have created a custom fee field, say PF_AUTHOR_FEE. I have another custom fee field PF_DISCOUNT. On the global form, I need to calculate the fee after the discount. I use the expression:
[PF_AUTHOR_FEE]*[PF_DISCOUNT].
The fee becomes zero. It appears that the custom fields are not recognized by the script. Only field I can use is [FIELD_VALUE] and constants.
Even on the PF_AUTHOR_FEE sheet, I cannot use [PF_DISCOUNT]. All fields are dropdown type with default values defined.
Also, how do I use the total form value (not field value) in script? Is there a term FORM_VALUE?
Thanks

Never mind.
I guess I figured it out.
Thanks

Hi,
I guess there is no variable [FORM_VALUE}. As of now I can manage using just the [FIELD_VALUE].
Follow-up questions:
1. How do I change the column widths? I need to make them wider.
2. How do I assign a different layout to a form/field? I don't see the option anywhere. The one on the field management is just a text box with no selections available?
Thanks

1. How do I change the column widths? I need to make them wider.

=> Could you please send me the link to the page ? I will look at it and then guide you. It should be simple CSS modification.

2. How do I assign a different layout to a form/field? I don't see the option anywhere. The one on the field management is just a text box with no selections available?

=> I don't understand this question. I believe each custom field doesn't have different layouts to choose from. Maybe I mis-understood your requirement ?

AN>>Regarding the layout, I understand that there are 4 different layouts available that one could choose from. How do I choose one of these layouts?

Any answer please!
