Changing "cm" to "mm" in Numinix Extra Product Fields mod

Hi,

I installed the Numinix Extra Product Fields mod and everything is working great, the only problem I'm having is figuring out how to chage the "cm" to "mm" on my product page. I was able to change it in the admin, but wasn't able to figure out how to change it for the product page. In the database there is a column called products_dim_type which is where "in" or "cm" is input, but even changing that to "mm" didn't seem to change it for the product page.

I hope it's ok I posted this here, I tried getting support on the Numinix forum but haven't even gotten my post approved to be put on their site, and I would like to get this resolved so I can move on. I thought since it's a free mod it might be ok to discuss here, plus I have a feeling it's something really simple.

Any help would be greatly appreciated!

Thanks
