How to use an argument while calling object using image repository.

If you're using JScript or JavaScript, a trick you can use is to use the [] notation instead of dot notation for objects to get around this.  So, change your code to the following:

function Test1(Row)
{

       ImageRepository.IDRowMillInch[Row].Click()
} 

function Run()

{

    Test1("HoleFeaCondCopy")

}
