new fields problem

[Dizzee]

I've tried to add new fields,
I have used a module provided to add product dimensions and configured it accordingly to my own requirements however the extra fields as ALL other fields except price and module do not display: even though the admin/conf../product listing is confiured as:
Title Value Action
Display Product Image 1
Display Product Manufaturer Name 1
Display Product Model 1
Display Product Name 1
Display Product Price 2
Display Product Quantity 1
Display Product Weight 1
Display Buy Now column 1
Display Category/Manufacturer Filter (0=disable; 1=enable) 1
Location of Prev/Next Navigation Bar (1-top, 2-bottom, 3-both) 2
Location of Prev/Next Navigation Bar (1-top, 2-bottom, 3-both) 3
Location of Prev/Next Navigation Bar (1-top, 2-bottom, 3-both) 2
Location of Prev/Next Navigation Bar (1-top, 2-bottom, 3-both) 1
Display Product Dimensions 1
Display Product Dimensions 1
Display Product Dimensions 1

I have followed the module as descibed in http://bronzemoon.co.uk/productdimensions.txt
except in .sql table [products] I have assigned products_lenght et al as varchar(64) instead of int
Any idea why no other fields are showing and as such how to get these fields showing?
The purpose is for a record store at www.bronzemoon.co.uk
thank you
