Using Nav Attribute in Input Ready Query

HI,

Is it possible to use Nav. Attributes in the ready for input query?

I am using one nav. attribute in the ready for input query, it is throwing error message when I click on SAVE button after entering some values as

Characteristic [0PRODORDER__0COORD_TYPE]Order Type is not filled by InfoProvider ABC.

[0PRODORDER__0COORD_TYPE]Order Type.

Any suggestions please.....

Thanks and Regards
