Using Substring Method In Function Breaks Other Strings

Question

I'm working on a function, which works fine except when I try to use the Substring method.

Once I add .substring(#,#) to any of the strings in my function, other strings seem to break.

Am I doing something wrong? I can't figure out a way to use substring() in a function without it breaking the function.

If I run my code outside of a function, everything seems to work fine.

function Get-String ($string1, $string2)
{
    return($string1.substring(0,1) + $string2)
}

Get-String("One"+"Two")

I'd expect this function to return "OTwo" It returns "O"

Replacing the variables with string literals resolves the issue.

You are concatenating the two strings into one string in the function call. Use Get-String "One" "Two" instead. Don't use brackets there, simply state the parameters separated by space. — Theo

Per Theo's comment: changed

Get-String("One"+"Two")

to

Get-String "One" "Two"

and everything works perfectly now.
