2. Then you would need to log in to your Shopify account and navigate to the page where you'd like to add your form. Click the < > icon in the top right corner of the text editor.
3. Paste the iFrame code into the text editor and then click the < > icon to exit HTML code mode.
4. Finally, click 'Save' and view your published page. If you'd like to adjust the height or width of the iFrame, return to the Page editor, click on the HTML code button and change the height and width amounts in the code, then re-save the page.
