Script stops execution when faces an error

I have a master script master.ps1 which calls two scripts One.ps1 and Two.ps1 like:

&".\One.ps1"
&".\Two.ps1"

When the One.ps1 script has an error, the execution gets stopped without continuing the execution of Two.ps1

How to continue execution of Two.ps1 even if there is an error in One.ps1?

@Martin is correct assuming that the success or failure of .\One.ps1 does not impact .\Two.ps1 and if you don't care about logging or otherwise dealing with the error. but if you would prefer to handle the error rather than just continue past it you could also use a Try{}Catch{} block as below to log the error (or take any other action you would like in the Catch{})

Try{
  &".\One.ps1"
} Catch {
  $error | Out-File "OneError.txt"
}
Try{
  &".\Two.ps1"
} Catch {
  $error | Out-File "TwoError.txt"
}

Other ways to format this but you get the idea.

You have to set the $ErrorActionPreference to continue:

Determines how Windows PowerShell responds to a non-terminating
error (an error that does not stop the cmdlet processing) at the
command line or in a script, cmdlet, or provider, such as the
generated by the Write-Error cmdlet. 

You can also use the ErrorAction common parameter of a cmdlet to 
override the preference for a specific command.

Source.

$ErrorActionPreference = 'continue'

Note: As a best practice I would recommend to first determine the current error action preference, store it in a variable and reset it after your script:

$currentEAP = $ErrorActionPreference
$ErrorActionPreference = 'continue'
&".\One.ps1"
&".\Two.ps1"
$ErrorActionPreference = $currentEAP
