Instead of providing a link to the general Fundraiser donation page, can you get a link for the donation page of a specific solicitor?
1. Access the solicitor's Individual page 2. Click the Donate Link 3. Copy the URL entirely. It will look something like this: https://localhost/NetCommunity/SSLPage.aspx?pid=204&tab=3&frsid=14 4. Email the link
The key is to make sure you are providing a link that includes FRSID in the URL. This stands for Fundraiser Solicitor ID, and identifies the unique solicitor to be associated with the donation from the form (note this solicitor ID is solicitor 14 from sample data, and your FRSID will be different for each solicitor). This will cause the gift to come into Raiser's Edge with the solicitor information attached.
