How can I add a signup form to my wordpress.com sidebar

I've been trying to add a form to my sidebar, but all I get is the code posted, not the form. I can post it as a separate post, but I don't want that. As it's a signup form, I would like it to be visible all the time in my sidebar.

Please help.

Please try using the SHORTCODE embed as discussed on this guide below:

How-to-Embed-a-Form-to-Wordpress-com

Please try that and let us know how it goes.

Or you can also embed your form's iframe embed code directly on your WP sidebar using the basic Text Widget. This should work. Make sure to paste the code under the Text tab as shown in this example below:

I tried your suggestions and used the iframe embed code. I got the same thing--the code appears but not the form. This happens every time, both with you and mailchimp.

Could you please try using a SHORTCODE of the form? Here's an example:

[embed]https://form.jotform.com/form/200426248523954[/embed]

This works on my end so I hope the same works on your page too.

Also, could you please provide us the link to page your working on so we could also check?

Hi. I replied to this email the next day, including the link to my blog. I'm wondering if it actually arrived, as I've had no reply to date.
I have already used the shortcode. That was where I started! Everything posts the code, not the subscribe button, unless I post it as a new post, when it works.
But I want it to be on the sidebar, not as a separate post, which will be lost when I post the next one.

Hi Vivienne,

Please try again my colleague's advice and kindly make sure that you have pasted the iFrame code under the Text Widget. As shown in this example:

If you have already tried it and still showing the same problem kindly provide us the screenshot of the issue and how's the code posted on the Wordpress sidebar.

Please follow this guide to post your screenshot as we are unable to view attached images on emails: How-to-Post-Screenshots-to-Our-Support-Forum

Looking forward to your response.

Thank you for providing the screenshot, may I also ask for the screenshot of how the codes are embedded in the Main Sidebar on Wordpress site, to assist you better? 

Looking forward to your response.

Sorry, I don't understand what you want.

My apologies for the confusion I created. 

May I verify if you have used the Text widget to insert the iFrame codes on the Sidebar?

If not, please try it on your end and let us know how it goes.

Hi.
Yes, I did use the text widget.

For WordPress.com, you need to follow our steps from this guide: https://www.jotform.com/help/299-How-to-Embed-a-Form-to-Wordpress-com.

For the Widget Section in WordPress.com, I'm afraid it won't display properly. I would suggest embedding the form on a post or page and just redirect users to this page through your Sidebar. You can add a button or an image as a placeholder.

Hi.
Thank you for your help. I 'll do as you suggest. A good idea.
Best wishes
