The Webstyle Frontpage Add-In is not compatible with Microsoft Expression Web; therefore you must import nav bars and graphics generated in Webstyle manually into Expression.
Please follow these steps:
Click the Save button
Configure the graphic export options and select the project you wish to save the template into, then select Save Graphic.
At this stage you can select the location where the NavBar will be saved. Save your NavBar files in the same folder as your Expression website as this will make it easier to import into Expression later.

Browse to the folder where you put your saved files and open the HTML file generated by Webstyle, in Internet Explorer. It will have the name you gave to your webstyle saved files (e.g. windows-co.html in the example.)

Click to allow blocked content, note the Information Bar will not appear when the project is uploaded to the web. For more information see 'My Menu Maker/Webstyle NavBar or photo album does not display when viewing my web page locally'
In Internet Explorer 6 go to View > View Source
or in Internet Explorer 7 go to Page > View Source
Copy the script snippet which will be in the form:
<script src="xaramenu.js"></script><script Webstyle4 src="project_name.js"></script>

Open Expression and switch to Code View

Paste the code snippet between the <body> and </body> tags

In Expression switch back to Design View
Select:
View > Formatting Marks > Show
then
View > Formatting Marks > Script Blocks
The scroll icons denote where the Webstyle content will appear on the page
