Change language on buttons

Hi,
I have downloaded the Swedish version of the Polldaddy but are not able to find the way to change the language on the Vote-button and the View Result-button to Swedish. I have examined the css but cannot find the correct html-codes to change.
Veru grateful for your help and advice.

Kindest regards
