Problem getting UsesRemaining value through to the script's Timer

I have worked on this script now for over three days. Yes I know . . silly fellow.

I have been trying to make a quest reward 'Shroud' with the following features:
1) it turns the wearer Invisible
2) it increases the the wearer's Hiding and Stealth skill while worn
3) it gets removed after a short period of time (I used 10 seconds for testing) so they cannot just walk around with it on all the time
4) it resets their Hiding and Stealth skill when it gets removed
5) it has a limited number of uses (10)
6) it drops into their backpack when it gets removed and shows the reduced number of uses

The script I made compiles and everything seems to work 'Except' the new Shroud that gets dropped into their backpack does not show the correct reduced number of uses. Actually the new Shroud shows zero uses.

I am not able to carry the value of UsesRemaining from the Shroud into the Shroud's Timer . . . just too much above my scripting grade.

My last attempt to get this working gives me an Error.

Here is the error:
Code: 
Errors:

If anyone knows how to solve this it would be appreciated.

Hey,

the reason you're getting that error is because you are trying to access the variable in the shroud, you need to store the shroud somewhere and then access it from that variable. (See this link: Compiler Error CS0038)

I modified your code, you pretty much overcomplicated the timer, it is much simpler and you also don't need to create the shroud new each time :)

haven't tested it but i think this should work:

C#: 
using System;
using Server;
using Server.Misc;
using Server.Items;
using Server.Network;
using Server.Mobiles;
using Server.Targeting;
using Server.Accounting;
using System.Collections;

        private SkillMod m_SkillMod0;
        private SkillMod m_SkillMod1;

        private int m_UsesRemaining;
        private bool m_ShowUsesRemaining;

        [CommandProperty(AccessLevel.GameMaster)]
        public int UsesRemaining
        {
            get { return m_UsesRemaining; }
            set
            {
                m_UsesRemaining = value;
                InvalidateProperties();
            }
        }

        [CommandProperty(AccessLevel.GameMaster)]

Well I can think of two words . . . Wow and WOW.

I appreciate this a lot both for speed and for success. You not only helped me solve a problem, you also taught me something that I hope will avoid a similar one later.

While I'm not great at 'speaking C# I do know enough of it to appreciate when I see it 'spoken' so eloquently as is is from you.

Many thanks.
