# [SOLVED] For Loop not counting properly

## Issue

The prompt for the exercise is as follows:

Uses a for loop to sum count values from start by increment.
Use: total = sum_count(start, increment, count)
Parameters:
start – the range start value (int)
increment – the range increment (int)
count – the number of values in the range (int)

What i’ve come up with:

``````def sum_count(start, increment, count):
total = start
for i in range(start, count):
i += increment
total += i
else:
``````

When i call and print the function using values 2, 2, 5, the return should be 30, however I am only returning a value of 17. Which part of my code is wrong?

## Solution

If you want to repeat something `x` times, you can use a loop `for _ in range(x)` that doesn’t do anything with the value `_` itself.

Use a for loop to sum `count` values from `start` by `increment`

means that `count` is not the upper boundary of the range – that’s what you did – but the number of values to add up. So for `count` times, increase the `start` value by `increment` and take the sum of the values.

``````def sum_count(start, increment, count):
total = 0

for _ in range(count):
total += start
start += increment
