Modifying Free Amount to Hide Products

[Guest]

I attempting to configure the freeamount free ship module to hide or exclude certain products from free shipping.

 

Currently the option to exclude items listed on special is available, I want to be able to exclude any product the same way.

 

I am a total newbie at this and find myself in very deep trying to do this. In an attempt to figure out how the hiding specials worked, I tried to change the script in the freeamount.php to call featured products rather then specials, to no avail.

 

I am hoping someone with more knowledge can explain some of the things i will have to do to be able to exclude whatever products i would like using the freeamount add on.

 

 

here is the free amount shipping module. any insight would be greatly appreciated.
