    Asked on September 01, 2015 at 01:21 PM

    I am putting numbers into a Numeric Text Box Matrix in form KSIM BA.  The numbers are -2, -1.5, -1, -0.5, 0, 0.5, 1, 1.5 and 2, but I am getting the error that only numeric values are allowed.  Aren't these numeric?

    It seems to me that you appear to be having some issues with numeric validation in your matrix.

    However, when I tested this I found it is working normally on my end as I was unable to replicate the problem that you've mentioned after testing it on your form.

    The only time I found the validation warning appear was when I entered in the " - " hyphen as a negative symbol but after typing in the numeric value then it went back to normal with no issue.

    Thank you for your assistance. Yes, I found that it worked fine when I opened up another version of the form.
    I may have had a hyphen or a comma slip in there by mistake. I noticed that the boxes turned red, but I kept on going because I didn’t know what that mean. I didn’t see the warning until I scrolled down to submit. After that, the form froze.

    If you are taking suggestions, you might also disable input and make the warning visible when the offending character is entered. With that, I might have been able to recover.

    I’ve got a lot of data in there now. Is there any way to unfreeze the form?

    Otherwise, thanks again for your help…

    We can take your suggestions and we can forward it to our developers as a feature request. Although, we might need more information or specification on how you would like it to work.

    Currently, this is how the validation works, when you enter a non-valid data, it will automatically show the error highlight color

    If you want to have a more visible highlight color, we can change it using the Form Designer Tool or a custom CSS code. Here's a sample code:

    input.form-validation-error {

        border: 2px solid red !important;

        box-shadow: 0 0 3px red !important;


    You can check my cloned form here: You'll see that the specific input with validation error is now more brighter or have a solid color.



    For the other issue that you are having with regards to the form freezing after clicking submit, please refer to this link instead: I opened a new thread so that we can focus on it better. We will address that shortly.

    Thank you.
