I have a case where I do a query, but I do not know how many answers I will get.
So I have to loop through a variable number of tags.

One way to go is ask the user to decide how many times he wants to loop
(assuming the user knows the number of query answers).

I have tried to use "Last Tag Number" = RSSInput.value1 "From First".
My value1 is equal to 2, but it does not seem to work.
Only numbers seem to be accepted.

What is the way to do this?


An other question: is there a way to go around errors when a tag is not found?
I put "On error, skip branch" in the "For each tag" action, but this still gives an error.

[edit] To explain more what I want to do. It is very similar to the tutorial on your site with Digg.
The main difference is that the number of answers that I want to return is chosen by the user (for example: first 3 answers),
and that the search query might return 1 or zero answer, so I have to handle the case where a tag for the answer is not found.

As my tag line indicated, everything is possible in a robot. It's just a matter of figuring out how to do it.

In this case, what you have to do it custom design your own looping, which will break once a given criteria is meet. This service show how it can be done:

As you will see, it is not simple, but doable. And actually it solves a previous issue posted regarding exiting a loop based on a condition. Anyway I hope you find this service/robot useful.

Kind regards,

"Is it possible for a robot to ..." but rather:

Thank-you, this was very helpful.
