My guess is that there are some hidden characters in your string that you are not seeing. Are you sure your string is reallly "123" or are you grabbing it from another function call or input. You can easily tests this by simply setting


MyCompany1 = "123";


then running your convert. It works fine on my end. good luck!
Reply:MyCompanyID1 can't be a string containing "123", because you've already declared it as an integer.
