Thread:User talk:Rua/Reverted changes

Hi, I just tried to correct some reconstructed data I found (https://en.wiktionary.org/wiki/Reconstruction:Proto-Slavic/so%C4%8Diti), I got a code error, and before I was able to find what the error was, you reverted my edit. Would you like to tell me why? I have referencess based on which I made the correction.

Also: what would be the Old Polish language code? The template was not able to process the one given here https://en.wiktionary.org/wiki/Category:Old_Polish_language
