launching a ural in multiple web browsers simultaneously

Hi experts,

I'm trying to create a batch file that when I double click on it, it opens a url in mulitple web browsers at the same time.

So my batch file is called mytest.bat

This is my code.

set /p url= [https://www.bing.com]

if exist "C:\Program Files\Internet Explorer\iexplore.exe" start "" "C:\Program Files\Internet Explorer\iexplore.exe" %url%&
if exist "C:\Program Files%(x86)\Mozilla%Firefox\firefox.exe" start "" "C:\Program Files%(x86)\Mozilla%Firefox\firefox.exe" %url%&
if exist "%ProgramFiles(x86)%\Opera\opera.exe" start "" "%ProgramFiles(x86)%\Opera\opera.exe" %url%&
if exist "%ProgramFiles(x86)%\Safari\Safari.exe" start "" "%ProgramFiles(x86)%\Safari\Safari.exe" %url%&
if exist "%USERPROFILE%\AppData\Local\Google\Chrome\Application\chrome.exe" start "" "%USERPROFILE%\AppData\Local\Google\Chrome\Application\chrome.exe" %url%&

Select allOpen in new window

But something is not correct.

What I'm a doing wrong? or is there a better way to do the same thing?
