vb.net scripting in vMix

I have a script (requested from the software developers support dept) that opens the last recorded video in vMix as a new inp(live streaming software). this can be seen at [login to view URL] This works well but i would like to extend it to send the newly opened input to program (ie play it). My VB skills are not good and I have probably exhausted what support will do for me. I need someone to install the free 60 day trial of vMix, install the script and extend it to add this functionality. it's not a big job at all but not some I can do. I would make a video showing how to setup the software and script so that it is clear what needs doing and how to test the extended functionality. I will need more scripting completed in the future for this so there is more advanced work to come soon. Alex
