InstallAware

I am trying to build an install at the moment for our application that uses an Oracle backend. I have the installer working fine for the application and I am now trying to add some extra bits to help with the set-up. I need to browse to the directory that contains the Oracle TNSNames file. I am using the destination dialog again, and I am saving the TARGETDIR into a temp variable then setting TARGETDIR to the default directory to browse to. The problem I get is when you then click the browse button and select a different directory this gets appended into the directory name already there, i.e. I set c:\\bar and then browse to the directory c:\\foo the variable gets set to c:\\foo\\bar. If I comment out the two 'set variable' commands the dialog works correctly.
Can anyone help me with a suggestion of how to do a second directory browse to work? I am sure I am missing something simple.

here is the code

You can actually merge both fields into the same dialog now. Please see the new feature description/how to's for the InstallAware 6.5 release on this forum. There was a step by step guide there on how to do that.
