let me know if you can help me solve the issue

4

please describe it in your own words, what does it ask you to do?

5

it want me to run lambda function in total expense and add paramter expense in it can you please look into this?

6

ok, and do you think you did that?

7

i am not sure its a quite challenging what i have input there can you please look into this?

8

You are not sure you created a lambda function?

is that code you wrote yourself? or did you copy it from somewhere?

9

i wrote it myself but i am not sure how can i go forward in this

10

if you wrote it yourself, what made you write sum and map? where did you find the indication to write those?

11

i read question very carefully

12

and what part of it mention using sum and map?

13

in one of the step they want to add sum and map to the code if you feel i am bluffing check 2-3 steps back you will get it

14

You are wrong, past steps do not want map and sum, it’s future steps.

To solve this step you need to do only and exactly what you are asked to do, which is create the lambda function

15

ok let me try that and will get back to you

16

got it thanks for the help
