Or is the problem they might not actually upload that number of images and you want a 100% accurate number? </p> https://legacy.forums.gravityhelp.com/topic/dynamically-add-image-upload-qty-to-hidden-field#post-36871 Mon, 03 Oct 2011 05:59:49 +0000 Huw Rowlands 36871@https://legacy.forums.gravityhelp.com/ <p>Hi,</p> <p>I have a form that allows users to choose how many photos to upload.<br /> First they have to choose from the drop-down 'How many photos?", which then displays the correct amount of Image Upload fields.<br /> I have setup a hidden field which I want to store the result in. How do I dynamically get the answer? How many photo's are my user's uploading?</p> <p>Thanks </p>
