Sum two lists

Hello everyone!
I want to sum the elevation survey point to all my spot elevation tags, then change the parameter name suffix with the total value of that sum is that posibble?

Thanks in advance

Just use an + node. Feed in your list and feed in the 1.
It will spit out a list, each number will have 1 added.

Then use SetParameterValueByName to change the parameter.

That’s not the plus node haha.
Just search for “+”

Lol yeah!
Thanks guys!
so how can i add this diagonal before?
Also I got this error message?

Check the type of the parameter, if it is string make the numbers strings before feeding them
