Hi Yafim.
Can you please elaborate what you are trying to achieve when the “Submit” (button6) button is pressed?
I see your code there is:
$w("#dataset1").onReady(() => {
This code as per API reference http://www.wix.com/code/reference/wix-dataset.html#onReady, is setting a handler for the dataset1 to run automatically when it is ready.
Regards,
Genry.
