Cannot print tax receipts!

Hello,

Typically we 'save as' the tessitura 'letters' report into an excel and copy and paste into the RAW tab of another excel document. This is supposed to link to a word document for tax receipts and letters. For some reason they are no longer linking and I cannot print any receipts.

I am unfamiliar with Tessitura tax receipting - can someone please tell me where to start looking and how to fix?

Thanks!
