+# Bicep warning and error code - BCP072
+
+This error occurs when you reference a variable in parameter default values.
+
+## Error description
+
+`This symbol cannot be referenced here. Only other parameters can be referenced in parameter default values.`
+
+## Solution
+
+Reference another parameter instead.  
+
+## Examples
+
+The following example raises the error because the parameter default value references a variable:
+
+```bicep
+param foo string = bar
+
+var bar = 'HelloWorld!'
+```
+
+You can fix the error by referencing another parameter:
+
+```bicep
+param foo string = bar
+param bar string = 'HelloWorld!'
+
+output outValue string = foo
+```
+
+## Next steps
