Translate fields language or delete

I can not find where to translate or delete fields called 'Brand' and 'Availability'. Also I get OT_VIRTUEMART_PRODUCT_OUTSTOCK
I also want to translate: 'Roll over image to zoom in'
Thank you very much!

Example:
www.pixelatumente.es/ortomediterraneo/in.../la-cannonata-detail

Hi,
Please translate it in /language/en-GB/en-GB.tpl_ot_valupat.ini.
If you have multilingual site (eg: English, Espanol), copy above file to /language/es-ES/ and rename to es-ES.tpl_ot_valupat.ini and then translate.

Remember save it in utf-8 (with/without BOM)

Thanks

I created the duplicate following the instructions and does not work.
I even temporarily deleted the file /language/en-GB/en-GB.tpl_ot_valupat.ini. and did not appreciate changes.
it's like not connect with the translation file. I think...

Thanks a lot!

Example:
www.pixelatumente.es/ortomediterraneo/in.../la-cannonata-detail

I tried the Spanish translation does not work. Nor results with the original file-GB.tpl_ot_valupat.ini

........................
es-ES.tpl_ot_valupat.ini (last 3 lines)
........................

OT_VIRTUEMART_PRODUCT_INSTOCK = "En Stock "
OT_Product_SKU = "Código: "
OT_Brand = "Marca: "

........................
en-GB.tpl_ot_valupat.ini (last 3 lines)
........................
OT_VIRTUEMART_PRODUCT_INSTOCK = "En Stock "
OT_Product_SKU = "Código: "
OT_Brand = "Marca: "

Neither translated texts...
Seems that the template does not connect to the translation file

Any solution linh_omg?
