    What is the error (number and message)?
    We don't have access to your table definitions and data, so we cannot replicate the issue.

    My guess is that the varchar column container other than numeric data.
    You can find them by using

    WHERE TRY_CAST([yourVarcharCol] as float) IS NULL  

    TRY_CAST documentation:
