The value of the variable "result" is never set anywhere in the code. In other words, variable "result" is declared but never given a value.

Explanation:

The call to the function "tenPercent (value) " on line 8 of the code returns the product of "value" and 0.1 i. e value * 0.1 as stated in the function declaration on lines 14, 15 and 16.

The returned value from this call to the function "tenPercent (value) " should be stored in the variable "result". This can then be displayed as written on line 10.
