Hi All,
I m working on a project that has different sub-projects. I would like to include a link to a file that is placed in another folder. For ex. My file whose path is ProjB/FolderB/FileB.asp --I want to write a line of code that will enable me to link to a file whose path is ProjA/FolderA/FileA.asp.
Can I achieve this using the navigateURL command?How?
Thanks in advance.
