An algorithm is designed to validate the weight of a suitcase (in kg) to ensure it is between 1 kg and 23 kg inclusive.

Figure 1

1  validWeight ← False
2  REPEAT
3      OUTPUT 'Enter suitcase weight in kg:'
4      weight ← USERINPUT
5      IF weight < 1 THEN
6          OUTPUT 'Weight must be at least 1 kg'
7      ELSE
8          IF weight < 23 THEN
9              OUTPUT 'Weight must not exceed 23 kg'
10         ELSE
11             validWeight ← True
12         ENDIF
13     ENDIF
14 UNTIL validWeight = True

The algorithm in Figure 1 contains a logic error on line 8.
