The previous attempts failed because: 1) Valuation contains 'n/a' values that can't be cast to DECIMAL, and 2) I used the wrong column name 'Date_reported' instead of 'Date reported'. I'll start by examining the distributions of Amount and Valuation to understand their values, then compute correlations between numeric measures while handling the 'n/a' values properly. Let me first check what values exist in Valuation.",
