Hello everyone.
I want to update a date card inside a form when a button is pressed. At the same time, that button submits the form after variable is updated.

On Start button, i have this code below:

I can achieve that with the above code, but after the submission the result is not the same.
On default property for my Check Out date / time value i have:

If I have a different button with SubmitForm() code everything works fine. Could I do the same with just one button? Update variable on the form (date) and after that submit the form.
Any help appreciate it.
Thank you.
Nick
