BCE0004: Ambiguous reference 'Label'

Hi there i have a possible stupid question but hang in there. When i went into playmode with this script it worked just fine but when i went to build it it came up with this error:

Assets/Assets/scripts/Character menus/character skills.js(221,34): BCE0004: Ambiguous reference ‘Label’: UnityEngine.GUI.Label(UnityEngine.Rect, UnityEngine.GUIContent), UnityEngine.GUI.Label(UnityEngine.Rect, UnityEngine.Texture), UnityEngine.GUI.Label(UnityEngine.Rect, String).

here is a copy of the script:

any help would be greatly appreciated thanks.

It sounds from the error like Unity is complaining that your variable isn’t strongly typed: you’ve defined “var [name]” without defining the type (e.g. “var [name] : [type]”) for a number of different variables. It may be that when running in the editor Unity can figure out what type of label to use at runtime, but when compiling it needs to compile the code it doesn’t know what to compile for.

You can solve this by defining a type for variable used in the line referenced by the error (e.g. var myVar : string;). You can also set #pragma strict, which forces you to type your variables and avoids this kind of thing in the future. It’s a good idea to do this anyway - it will make your code (especially with so many variables as you have here) run faster.
