title: Finding Lookup item numerical values in MS Dynamics
body: <p>I have a site powered by ExpressionEngine 2.5.x, using Freeform, integrated to post form data to MS Dynamics CRM 2011. The extension is nicely scalable, I can change the mapping, all that excellent stuff. My problem is how to find mapping values for Lookup fields in MS Dynamics.</p>
  
  <p>I am trying to map form fields from the site forms, into MS Dynamics. Some of the fields are Lookups, in MS Dynamics. Our mapping calls out the numerical value of the Lookup item, rather than its name. (Which is good, because ppl can change the text names in the MS Dynamics console without breaking the mapping.)</p>
  
  <p>My question is: I know how to find the actual back-end field names of form fields within MS Dynamics. But how to I find the numerical values of the picklist items and lookup fields? Say I have a Lookup field, for Lead Source (called campaignid). The items are:</p>
  
  <ul>
  <li>web  </li>
  <li>online  </li>
  <li>radio ad  </li>
  <li>flyer  </li>
  <li>word of mouth  </li>
  <li>other  </li>
  </ul>
  
  <p>I know that when I edit options in an option set, I can see their numerical value. Where can I edit options in a lookup field? I've tried looking under <em>Settings > Customizations > Customize the System</em>, but didn't see anything called <em>lookup</em>.</p>
