Iīd like to create a button (in a form) that will open an audio or video file at a specific point. I mean: instead of playing the video from the beginning, it should start playing at a specific moment inside the audio/video file. Please give me the full syntax. Thank you very much in advance!

The time in wich i want the file to start playing is stored in a field called 5_Section_Begin of a table called 5_Scetion (in minutes and seconds - xx:yy)

The path to the file to open is in a field called Chapter_Link of a table called 4_Chapter

Thank you very much in advance!
