There is no built-in way to enforce users to enter only one decimal digit. If you have PHP experience, you can use the gform_field_validation hook and a few lines of PHP code to perform a custom validation. The following page has information about that hook.<br /> <a href="http://www.gravityhelp.com/documentation/page/Gform_field_validation" rel="nofollow">http://www.gravityhelp.com/documentation/page/Gform_field_validation</a> </p> https://legacy.forums.gravityhelp.com/topic/number-fields-please-enter-a-valid-number-error-set-min-to-01-ex-12-27#post-42899 Fri, 02 Dec 2011 15:39:12 +0000 onmark 42899@https://legacy.forums.gravityhelp.com/ <p>Is there anyway to just disable number validation checking or to make this work?</p> <p>I have people entering orders that need to be down to the one tenth. I set the min value to 0.1 this worked when I set it to 0.01 for 1/100th entries i.e. 1.80 but it does not work upon setting it to 0.1 and entering 1.8.. only if I enter full 100ths even with the min setting at 0.1 </p>
