+## Variable names can't start with numbers, so this is interpreted as a command.
+
+### Problematic code:
+
+```sh
+411toppm=true
+```
+
+### Correct code:
+
+```sh
+_411toppm=true
+```
+
+### Rationale:
+
+You appear to be assigning to a variable name that starts with a digit. This is not allowed: variables must start with A-Z, a-z or _.
+
+Switch to a variable name that does not start with a digit.
+
+### Exceptions:
+
+None
