In the page, It has a series of checkbox. I want to checked all the options .

My RSS Robot looks like this:

Load Page > For each tag > Set checkbox(checked)> Extract value> Return RSS item。

The first option is ok ,But next iterate doesn't work 。Error as "The Set Checkbox action requires a found tag, but the tag finder did not find any tag. There is no tag that matches the attribute name and value."

If my RSS Robot looks like this :"Load Page > For each tag >  Extract value> Return RSS item", It is ok.

How can I checked all the option of checkbox???

Thanks for your product and your help !!!!
