Generate Yearly Report for Vendor – Click Activity

I am trying to implement below instruction of page no 4 of Generate Yearly Report for Vendor assignment since last 2 days, went through the forum but It didn’t help much, my click event is getting error out

“ Use a Click activity to select the processing page number using the same dynamic selector to identify the current page ( in_TransactionNumber argument). ”


Maybe tag is wrong,
You can use UI Explorer to confirm it.

*First time to open this page, I think no need to click the button [1]
