OnGUI errors but the script still runs.

[bumble864]

So I have a pretty large OnGUI code but I keep getting errors like this

ArgumentException: You can only call GUI functions from inside OnGUI.
UnityEngine.GUIUtility.CheckOnGUI () (at C:/BuildAgent/work/6bc5f79e0a4296d6/Runtime/ExportGenerated/Editor/GUIUtility.cs:391)
UnityEngine.GUI.Button (Rect position, UnityEngine.GUIContent content, UnityEngine.GUIStyle style) (at C:/BuildAgent/work/6bc5f79e0a4296d6/Runtime/ExportGenerated/Editor/GUI.cs:196)
UnityEngine.GUI.Button (Rect position, System.String text) (at C:/BuildAgent/work/6bc5f79e0a4296d6/Runtime/ExportGenerated/Editor/GUI.cs:190)
MainMenu_Script+$ShowSelectMission$43+$.MoveNext () (at Assets/Programming/scripts/Scene Scripts/MainMenu_Script.js:136)

when I double click it it takes me to something like this

//Missions
if (GUI.Button(Rect(85,240,100,100),“”)){
missionnumber=0;
audio.PlayOneShot(Select);
currentPage = Page.None;
SelectMission_OFF();
yield WaitForSeconds(1.0);
MissionDetails_ON ();
}

but the script still runs it just puts lots of those errors up and I can’t figure out why.

Any ideas?

Thanks

From the errors you are receiving, specifically “ArgumentException: You can only call GUI functions from inside OnGUI.”

I would have to guess that you are not calling your GUI functions from within OnGUI.
