How to count Records in a Table and/or Form

$

I have a Table which is being passed to my context in the ADOBE Form.  I need to be able to count the # of records in this table.  I don’t have to display the actual table in this case on the form, I just need the record count.  And, I need to do this using JavaScript and I don’t know anything about Java (although if FormCalc works I can use this as well).     My Tablename is Customer and on my form it is in the Hierarcy data.main.customerbody.customerline.  If I have to have this table data on the form then I can just put it on the form and make it invisiible.  I really only need to count the # of records though and return this # to a Text Field on the form.

 

Does someone know how to do this and can you give me an example in either Java for FormCalc?  The more specfic you can be with the scripting example the better for this newbie.  thx!
