Changing the text on notification of a size of a product out of stock

[bqi1735]

Hi!

 

Can anyone advice me on how to change the prompt message displayed when i.e. a particular size of a product is out of stock?  Currently the standard message that is displayed is " This product is no longer in stock with those attributes but is available with others"  and I wanted to change it to simply "The size you have chosen is out of stock" .

 

Appreciate if someone can advice me.

 

Thank you.

 

p.s I am currently using version 1.6.1.15
