Hi All,

I’m trying to execute the following code.

url = “[https://xxx.com](https://xxx.com)”(some url)  
ebay\_data = Scrubyt::Extractor.define :agent =\> :firefox do  
fetch(url)  
fill\_textfield field name, value  
record “//table[@id=‘header’]” do  
name “//input[@class=‘req’]”  
end  
end

Code executes properly for static name of textfield

But the url which i’m trying to fetch is having dynamic name so when i  
try to run the code it gives me error:

Unable to locate element, using :name, “”  
(Watir::Exception::UnknownObjectException)

Every time the name changes on refresh. Please suggest me how should I  
fill the text field of a url with dynamic text\_field name. (Using  
Scrubyt)

Thanks  
Saurabh
