HexSys Size Plugin for Virtuemart LIKE the DEMO!

Hello again,
Can you please help me with the values I have to put? I need to calculate width x height x price = totalPrice no mater what size inserts the user.

If I eliminate the values 1;2;3;4;5;6;7;8 and save, they appear again.
I think I dont need it, but I am not sure what it is, do I?

Hope you could help me with this!
Thank you in advance!

Hello,

I installed the plugin HexSys Size Plugin for Virtuemart Documentation
I read the documentation but cannot figure out and manage to make it work as good as it is working in your demo link.
Can you please tell me the configuration of the demo?
I need it exactely as the demo with the free text fields
www.demo.wdmtech.com/hexsys-size-plugin-...mart-free-textfields
an X between the two fields and multiply the amount the user puts in the fields with the price of the product.
I dont think I need the fields
Upto (Sq Unit)________ Price (Rate Per Sq Unit)___________
How can I eliminate them?

I also dont think I need
Width 1;2;3;4;5;6;7;8
Height 1;2;3;4;5

Also can I have default value the value 1 in both fields (width and height)?

Do you need backend/admin access?
Thank you in advance!
