CSS Selector with variable

[hibinoma]

Could anyone advice me about above Subject?

I want to loop each rows of a html page having table tag.
So I set the CSS selector as below.

However it doesn't work even though I forced the %RowIndex% as number 0 before running the step.
Is this usage incorrect? 
If give the setting back  to original, it dose works. 

Just changed the orignal selector from
 div[Id="sr"] > div[Class="basicsearchresults"] > table > tbody > tr:eq(0)      

to

 div[Id="sr"] > div[Class="basicsearchresults"] > table > tbody > tr:eq(%RowIndex%)  

Reards,

Did you change the selector builder mode to custom?

[hibinoma]

Thank you for quick reply.
Yes, I set to custom as below image.

You need to toggle it to the left. Right now it actually on the visual builder setting.

Those "checkboxes" and their text don't make any sense...

It looks work by set it to the left, thank you.
However..., after that ,

I tried to back to the builder setting page to modify it, but the toggle button looks gray out.
So I can't edit it anymore. Is this normal?

[Henrik_M]

Yeah, it's normal. Once it has been edited in custom, you can't change it back.

I guess if you want to keep a backup of a visual selector, you can press the New button in the selector overview before you make the selector custom, and then edit one of the parameters to something unrealistic, [class="visual backup"] for example.

I understood. Thank you for your advice.
