Form actions and functions with javascripting not performing same on users end?

[Anthony5E5C]

Does anyone know why certain actions I have javascripts for aren't performing the same on the users end when I email them the a fillable form I created?

I have a dropdown ("Vehicle Model") that will filter only specific options to select because its conditional upon what is selected in a previous dropdown (Vehicle Make).  However a user emailed me that when they selected a vehicle make, that when they clicked the arrow for the second dropdown to select the vehicle model specific to that make it didn't populate any options to select other that the default "-Select Model-".

I thought maybe was an error on my side in the scripting, but when I open and test the form on my end it works completely fine.

Another example, is that I have a lot of fields hidden with javascripts that should only become visible if certain check boxes are checked, but when the client downloads the PDF I sent them by email, it is by default revealing all the fields that I set to be by default hidden fields unless those boxes were checked.

Is the reason for the error is because of me adding the javascripting?  Is there a setting that needs to be checked in order for the scripting actions to perform on the form on the users end?

Does it matter the size of the file why this happens?   As currently my PDF form file size when attached to an email is about 5-6 MB in size.

If helpful I should also add that the issue seems to be global for who I sent the form to.  Those users who reported the issue to me used various mediums to open the file such as iphone, ipad, Macs, and Windows cpus, but all 5 people I sent form said they experienced same issue.

Appreciate any help community can offer to fix.  Thanks!

What app does the users use?

I had one user told me that they tried opening with their iphone and experienced the issue, so I assumed was an IOS issue.  However I advised them to download the Adobe Reader app and then try opening through adobe app but they indicated experiencing same issue where it appears the javascript actions aren't performing the same way as they do on my end when I have the form doc open.  I use Adobe Acrobat DC and was the version i used to create the form as well.

However another user who also has Adobe Acrobat DC installed on their PC said they to were having the same issue as the iphone user.

Almost no scripts work on mobile devices. On iOS devices the app that offers the best scripting support is currently PDF Expert by Readdle, not Adobe Reader.

However, if it indeed did not work for someone on a PC using Acrobat DC then there might be a different issue at hand here. Could you share the file, or at least the code, with us?

[Anthony5E5C]

Sure.  TY!  And thanks for that info.  Fair warning when you review my form it may be a little messy.  lol

This is actually my first go round with creating a PDF form using any kind of custom scripting and everything I've learned to do so far has been through tutorial vids or really mostly with help of this community.  And really this form is a temp a work around until some improvements are completed on our systems in the coming months.  

But yeah seems something is going on where my form and the scripting functions work perfect for me on my end, but everyone whos attempted to use or test my form doesn't appear to be working properly.

So far all my testers they have  Adobe Acrobat DC I believe 2015 version, but they all checked and said the  software was up to date with no updates available.  For myslef I also have "Adobe Acrobat Distller DC" which looks like some sort of PDF conversion program but I've never used but curious if maybe it is somethign needed so the script action perform correctly on user end.

Also on a separate issue but not sure if related to the reason my form scripting actions aren't working on the user end. But there seems to still be this issue when a form user attempted to click "Save PDF" button on form to save copy to their desktop, when they go back to open it from desktop all their responses are deleted?

Similar issue was occuring where some users reported when they attempted to submit the completed form via the green email form button I added on bottom that it was essentially triggering a reset form or clearing or erasing all the fields for some reason?

Appreciate the help.

There are errors in your code. For example, change the value of the "Vehicle 1 Make (Page 4)" field and then check the JS Console.

Or select an entry of the dropdown on the first page.

Commonly people are viewing the form in their email app or web browser. They assume that installing Reader will somehow change the other app to make it work, but that doesn't happen.
