create link to a forum using "title_clean" as tag?

[jfk1]

i see a lot of views to my post, but no replies which probably means i'm not asking the correct question.
here is what i want to do. i have created a list of vb_adv pages. i have created a list of vbul forums. both pages and forums are from the same list. i want to make a link from the "page" to the corresponding "forum" (and vice-versa) using $variable.
i know which data i want to look up, but my problem is that i dont know the syntax.
i would like vbull to look at the page it is currently displaying, using whatever $variable it used to create that page eg. sql_table "adv_pages"- field "title", then take this piece of data and go look in sql_table "forum"- field "title_clean", compare the data and return a match which then displays the relative forum.

i guess i've made this a complicated question again .... sorry.
