+# BizTools Examples Test Results
+
+## Working Examples
+- `bizmodel.vsh` - This example works correctly and displays a spreadsheet with business model data.
+
+## Non-Working Examples
+All other examples have issues with the `bizmodel.play()` function:
+
+1. `bizmodel1.vsh` - Error: Unknown field `heroscript` in struct literal of type `PlayBook`.
+2. `bizmodel2.vsh` - Error: Unknown field `heroscript` in struct literal of type `PlayBook`.
+3. `bizmodel_complete.vsh` - Error: Unknown field `heroscript_path` in struct literal of type `PlayBook`.
+4. `bizmodel_export.vsh` - Error: Unknown field `heroscript_path` in struct literal of type `PlayBook`.
+5. `bizmodel_full.vsh` - Error: Unknown field `heroscript_path` in struct literal of type `PlayBook`.
+6. `costs.vsh` - Error: Unknown field `heroscript` in struct literal of type `PlayBook`.
+7. `funding.vsh` - Error: Unknown field `heroscript` in struct literal of type `PlayBook`.
+8. `hr.vsh` - Error: Unknown field `heroscript` in struct literal of type `PlayBook`.
+
+## Common Error Pattern
+All non-working examples have the same pattern of errors:
+
+1. Unknown field (`heroscript` or `heroscript_path`) in struct literal of type `PlayBook`.
+2. Reference field `PlayBook.session` must be initialized.
+3. Function `bizmodel.play` parameter `plbook` is `mut`, so it requires `mut PlayBook{...}` instead.
+
+## Environment Setup
