Recursive Calculation let() List Loop Question

Hello all,

 

I am stuck on calculation that I cannot build the recursion into- I sucked at math, probably thats the problem.

 

Here is what I am trying to do:

Get a list of values. Go to the fist item of the list, do something with it and create a result,

go to the next item of the list; do something with it and create a result, add the result of this line to the result of the line before

end when I reached the last item of the list.

Output the result.

 

Here is what I have so far:

 

Let ([

list= List (of a field);

c=Valuecount (list);

$i = $i+1;

getitem=GetValue (list ; $i);

$result = getitem*dosomethingwithit

];

If ( $i = c; $result; getitem*dosomethingwithit + $result )

)

 

What am I doing wrong? I dont get the loop in my head in getting the calc to add to itself...

 

Thank you!
