Dear stevennestler,
It works fine on my end, you can post your code here, I can test it based on your code.
My test steps are as follows:
3. Switch to "HTML" and remove all content, copy the following html code there:
<iframe src="http://rcm.amazon.com/e/cm?t=xxx.com-xxx-20&o=1&p=12&l=ur1&category=electronicsrot&f=ifr" width="300" height="250" scrolling="no" border="0" marginwidth="0" style="border:none;" frameborder="0"></iframe>
4. Switch back to "Normal"
5. Click button "Save"
6. Open the access database and find the record has been stored in the DB
Thank you for asking
