Importing attribute values in taxonomy

Hi All,

I am trying to import attribute values as part of taxonomy import;but i am getting error saying that

some records failed to import.

Source file contains attributes and their corresponding values and mapped to corresponding destination

fields (Attribute Name and Text values).Attribute name acts as matching field and diplays match type as

exact and selected import action is either update all mapped fields or replace.

Can anyone tell me the solution?

Thanks
