Allowing only numbers to be entered in the Other field of a Check BoxAsked by Timothyink on August 31, 2016 at 02:56 PM
I have a need to only allow a number to be entered in the other category. I do not want to allow customers to enter text. Numbers only. Is there a way to do that?
We cannot limit the Other option of a Check Box field to accept only numeric entry, but we can achieve such a requirement by building our own "Other" option instead. We can do this by adding one more Number field to your form, and applying a show/hide conditional rule on it.
Here is how to achieve it, described in steps.
Step 1, adding a Number field to the form, and naming it "Other" or "Other Apparel Product". We will use this to get your "other" value, and since it is a number field, it will only accept numbers:
Step 2, access the settings of the Check Box field, by clicking on its gear-shaped icon (1):
Once it opens, switch to the Options tab (2), remove the custom Other option (3), and add an "Other" option among the regular options in your Check Box field:
Step 3, we finally set up 1 show conditional rule to show our Number field, if Other is selected in the Check Box:
