Product attribute Link

[genug023]

Hi,

 

I hope someone can help me with this. In my old shop 1.2.5 I used this productlink for google merchant center:

 

http://www.slaaptrends.nl/product.php?id_product=109&group_4=48

 

This linked directly to one of my products and then also to the correct product attribute..

 

However in my new shop 1.4.6.2 it doesn't seem to work anymore.

 

Can anyone help me find the new and correct link to a product an the correct attribute?

 

Thanks,

Michel
