Start the application on the browser of the form 5

3 - When I try to start the application on the browser of the form 5, although there are no errors in the program is set property of the first form = form1?
I repeated it with me in more than one project, and at first it works without problems, then this problem appears

It’s not clear what the problem is here - sounds like a problem in your logic. Are there any errors showing in the Chrome DevTools?

I don’t have any problem with the tools and I don’t get an error message, but it only starts with a different form from the first form that was set in the settings.

Please ,can you help me

You could also do this:

Function Main()
End Function

or JavaScript:

function Main() {
