Hi Frisco,
Here's how you could do it:
Let's assume that the two web apps are: 1- Hotels 2- Comments
The first thing to do would be to give the comments web app a data source of Hotels.
Next, use {module_url} on all links leading to the web app detail view.
Lastly, adjust the form's data source select tag then simply call the {module_url,*********} as the option value and the web app name as the option just like demo-ed below;
<select name="" id="" class="cat_dropdown">
<option value="{module_url,*********}" selected>{tag_name}</option>
</select>
Be sure to read up on the {module_url} via http://kb.worldsecuresystems.com/145/bc_1455.html?bc-partner
Good luck
