Some pointers.

• Always put use strict; and use warnings at the top of your scripts and declare your variables with my as this will save you time tracking down errors.

• Always indent your code to make it easier to follow the logical flow and be consistent.

• It is probably better not to have a scalar and an array both called value as this can lead to confusion. Make the array @values as it better describes its purpose.

• Why are you incrementing the $count by one every time through the loop rather than adding the value as entered and held in $line to it?

• Why are you spliting the each value into individual characters then setting $count to the number of characters (array in scalar context returns number of elements), thus undoing any previous work of accumulating a total?

Your problem lies with those last two points. Have a think about the logic required to accumulate a series of values.
