URGENT!! Custom Device Filter

[Rui Barbosa]

Hi to all,
I'm getting this error that i can't figure it out and i'm going crazy...

I'm trying to create a device filter using a custom filter type...
I'm doing everything by the book but i can't get rid of the error below.

Can anyone help...

The content of the Web.Config deviceFilter section tag is as follows
<deviceFilters>
<filter name="isJPhone" compare="Type" argument="J-Phone" />
<filter name="isHTML32" compare="PreferredRenderingType" argument="html32"
/>
<filter name="isWML11" compare="PreferredRenderingType" argument="wml11" />
<filter name="isCHTML10" compare="PreferredRenderingType" argument="chtml10"
/>
<filter name="isGoAmerica" compare="Browser" argument="Go.Web" />
<filter name="isMME" compare="Browser" argument="Microsoft Mobile Explorer"
/>
<filter name="isMyPalm" compare="Browser" argument="MyPalm" />
<filter name="isPocketIE" compare="Browser" argument="Pocket IE" />
<filter name="isUP3x" compare="Type" argument="Phone.com 3.x Browser" />
<filter name="isUP4x" compare="Type" argument="Phone.com 4.x Browser" />
<filter name="isEricssonR380" compare="Type" argument="Ericsson R380" />
<filter name="isNokia7110" compare="Type" argument="Nokia 7110" />
<filter name="prefersGIF" compare="PreferredImageMIME" argument="image/gif"
/>
<filter name="prefersWBMP" compare="PreferredImageMIME"
argument="image/vnd.wap.wbmp" />
<filter name="supportsColor" compare="IsColor" argument="true" />
<filter name="supportsCookies" compare="Cookies" argument="true" />
<filter name="supportsJavaScript" compare="Javascript" argument="true" />
<filter name="supportsVoiceCalls" compare="CanInitiateVoiceCall"
argument="true" />
<filter name="isWML" type="MyWeb.DeviceFilters.ExtendedFilters,
MyWeb.Controls.dll" method="IsWML" />
</deviceFilters>
