The problem is that if you copied and pasted this forum is adding spaces into the code to make it wrap. Try this:
WADbSearch1_whereClause=BuildKeyword(WADbSearch1_KeyArr0,"" & cStr(Request.Form("SearchBox")) & "","","Includes",",%20","%20OR%20","%22","%22",0,WADbSearch1_wildCard,WADbSearch1_dateSeparator,WADbSearch1_whereClause)
