How to open a popup on a button click event?

Hi dear @elenatsaruk ,
Thanks for your inquiry,

Let me guide you through the steps.

Please, head to your Form > Appearance > Popup. Change the “Loading Delay” to “-1”. Choose the page where your button is published.

After, please, copy the function under “Loading Delay” and paste it as “OnClick” action for your button.

Here is a recording with the steps.
Best Regards,
Mane

I’m ashamed, but I can’t figure out where to insert the function so that the button calls the popup.

Please show an example as you paste it as “OnClick” action for your button.

Dear @elenatsaruk ,
Sorry for a late answer.

I created an Custom HTML and it worked with no issues. Here is an example you can check.
