WAP Website Conversion

We have an English education website. It is in HTML, XML (XSL) and ASP.net. We have created a website in "raw" WAP/WML, but need it to work within our existing structure. It basically works, however, we need someone familiar with XML/ converting the pages to WML, and who can write simple functions that we already use in our XSL pages. An example: ? this code works in our standard xml/aspx pages, <xsl:variable name="res" select="func:GetResources($fpath,/props/@lang)" /> but when we try to use it in the wap pages, it breaks the page.
