Parsing parameters in WebApps

I’m trying to use the parm-parameter in the WebLink class: link = new WebLink(); link.menuFunction(New MenuFunction(menuItemDisplayStr(WebProductCatalogGroup),MenuItemType::Display)); link.record(inventProductGroup); link.parm(“Something”); The link.Url returns the correct URL, but when I click on the link the Parm (&WP=) is removed by Axapta This is the retun output from link.Url: default.asp?WMFN=WebProductCatalogItem&WMFT=D&WPG=EPHomepageOnline**&WP=Something**&WTID=935&WREC=332076889&WKEY=[65534:332076889]&WPEPHomePage=5Oversigt This is what the URL location says in the browser after I click default.asp?WMFN=WebProductCatalogItem&WMFT=D&WPG=EPHomepageOnline&WTID=935&WREC=332076889&WKEY=[65534:332076889]&WPEPHomePage=5Oversigt Any solutions to this?
