This is not a core formula from Gravity Forms, this snippet is taken from <a href="http://gravitywiz.com/subtotal-merge-tag-for-calculations/" rel="nofollow">http://gravitywiz.com/subtotal-merge-tag-for-calculations/</a> ... Not sure what exactly is wrong here, just to let you know!</p> <p>Thanks for the great support! </p> https://legacy.forums.gravityhelp.com/topic/calculate-field-error-eval#post-334047 Thu, 20 Jun 2013 06:28:46 +0000 pronamic 334047@https://legacy.forums.gravityhelp.com/ <p>The following formulie creates an error after completing an form:</p> <p>{subtotal} * 0.19</p> <p>The {subtotal} merge field is probably not allowed in the formule, but it's not very nice that this is causing an error.</p> <p>The 'eval' construction you use is probably not the best way to handle formules.</p> <p>Maybe you can improve this in a next release. </p>
