My source data link does not work and breaks at the + symbol?

If you use dynamic URLs for your content import and your URL contains a + (plus) symbol e.g. 

https://some.org/technical+program/ExhibitorExport?openagent, you must replace the symbol with %2B for the CMS to read it correctly. The above URL would now look like https://some.org/technical%2Bprogram/ExhibitorExport?openagent

1. Copy your URL into a text editing or note program
2. Paste the URL 
3. Replace the + with %2B
4. Copy the corrected URL and paste into the CMS
