Is there anyway the Total field can take the tax element and ad it together so its one price? </p> https://legacy.forums.gravityhelp.com/topic/add-tax-or-gst-to-total-or-live-update-of-enable-calculation#post-64985 Fri, 06 Jul 2012 08:48:52 +0000 Rob Harrell 64985@https://legacy.forums.gravityhelp.com/ <p>The best way to show the Tax and have it update the Total is on the Tax field - make that a calculation product field. Then add all of your products together with merge tags and then multiply it by the number. So your tax calculation field would look something like:</p> <p>(MergeTag1 + MergeTag2 + MergeTag3) * .1</p> <p>You may also need to factor in quantities too, but I'm not sure since I don't have a link to your form at the moment. </p> https://legacy.forums.gravityhelp.com/topic/add-tax-or-gst-to-total-or-live-update-of-enable-calculation#post-64946 Thu, 05 Jul 2012 22:37:12 +0000 Bobby 64946@https://legacy.forums.gravityhelp.com/ <p>I know there has been posts before, but i cant quite seem to get this to work.<br /> What i want to do, is either add 10% to the Total Cost on the fly OR have a GST component displayed as a number field with calculation.</p> <p>Currently i have a number field with calculation displaying the GST but it only seems to update on submit if I have {Total Report Cost:40}*.1, but if i use the products ie {product pear:61}*.1 the value is updated live.</p> <p>If anyone could give me a tip, would prefer the Total cost to have added 10% on the fly, but if thats too hard then the number field updated live based on Total would be great.</p> <p>Cheers. </p>
