I've been working on automating some steps on Craigslist so that all I have to do is enter the catchpa phrase at the end of the listing process, but I've run into a road block. It seems that the Form fields are dynamic, so I have to read the HTML to get the name. THe problem is, what I've got will work sometimes, and sometimes it will not, and so far I've not been able to click the submit button at the bottom of the first page. Here is what I've got so far. If anyone can offer any help it would be greatly appreciated.

Hi,

You can click a button if you know the name. In your case the name has an ID that changes.

A solution would be to submit the form with the Execute JavaScript action. Then you only need the form name, which has no ID that changes.

Typically with: theformname.submit;

See the last 2 lines in the attached script.
Hope this helps.
