The challenge with the selected web page is that
the fields are already present in the page but their style display attribute is set to none making the field invisible to the user but not to the software.
When scripting a webpage it does help to take a look at the source of the webpage.
Right click on the page and then select
View Source.
You will find the following HTML line
Code:
<tr id=companyRow style=display:none>
To check for this company textbox object to exist use the If Windows Object Exists approach.
Please see the attached zip file for reference.
