Require input field base upon another input field

[dufran3]

I have a gui with several input boxes. I have a If statement making the first 2 inputs required. How do I make is so that if someone types something in the input control $CollectEpisodeNumber, then the script will not continue unless something is also in the input control, $CollectEpisodeSeason. I will post the code I have.

    $Main = GUICreate('Newzbin Auto Downloader', 300, 150)
    Opt("GUICoordMode",1)
    $CollectName = GUICtrlCreateInput('',100,10,150)
    $NameLabel = GUICtrlCreateLabel('Name of Item',15,13)
    $CollectCategory = GUICtrlCreateCombo('',100,35,60,$CBS_UPPERCASE,$CBS_DROPDOWNLIST)
    GUICtrlSetData(-1,"Unknown|Anime|Apps|Books|Consoles|Emulation|Games|Misc|Movies|Music|PDA|TV")
