Here we go!...Got the [#] or [last()] conditions working...currently, it's simplistic, but the xpath your provided will function.

I also put in logic to allow for [last()-#], so instead of the last node, it will grab the 3rd to last...

Here are the new functions, and a sample of navigating through the new autoit forum, to the general help and support page, and then navigating the the 6th page...which is the last()-3:

$xpathGeneralHelpPagination = "//ul[@class='ipsPagination']/li[last()-3]/a"

using the same xpath, but wanting to grab the 3rd link would be

$xpathGeneralHelpPagination = "//ul[@class='ipsPagination']/li[3]/a"
