I am trying to create an order form.

I need to sell a product that is personalized is there away to add a text box, with a size limit, to an order form that it attached to the product?

Regarding your "adding a text box with size limit and attached to the product", can you please give us a bit detail about it so we can better understand to assist you?

The product is personalized with a message or an image.  I would like to be able to have customers enter their message into the form with a limit of 70 characters for one product or 140 characters for another.   If there is away for them to be able to upload an image that would be fantastic.

My other question is, if you don't offer that built in, is there away for me to embed a google form into a product page.

You can add a customize message field with character limit and also add an image to upload for the users using our conditional logic feature.

Please see this walk through image I created for you:

I hope this is what you were talking about.

If you have any further query, please let us know.
