Hi,

When my game boots, I have a StudioBankLoader components that loads my banks (including Master and Master.strings). I have a coroutine that checks if all the banks were loaded, then I set a global parameter from a StudioGlobalParameterTrigger like this:

```auto
[SerializeField] private StudioGlobalParameterTrigger _musicVolumeParameter;

private IEnumerator SetPlayerPrefsOptionsCoroutine(float intensity)
{
       // We wait so all the banks are loaded
       while (!RuntimeManager.HaveAllBanksLoaded)
       {
                yield return null;
       }

       _musicVolumeParameter.Value = intensity;
       _musicVolumeParameter.TriggerParameters();
}

```

But I get this error:

```auto
[FMOD] StudioGlobalParameterTrigger failed to set parameter MusicVolume_Fader : result = ERR_EVENT_NOTFOUND

```

One thing I noticed is that if I load the **Master bank** at the RuntimeManager initialization, it works. How? Why it doesn’t work even though I check if HaveAllBanksLoaded before using the global parameter??

Can someone help me understand this? 😌

Hi,

The issue is the `Global Parameter Trigger Script` is silently failing in its awake function. I have passed this on to our development team to look into further. Thank you for bringing this to our attention.

In the meantime, you can add the `Lookup()` function to the `TriggerParameters()` function to make sure you have a valid parameter.

```auto
public void TriggerParameters()
{
    FMOD.RESULT result = Lookup();
    if (result != FMOD.RESULT.OK)
    {
        Debug.Log(result.ToString());
    }

    if (!string.IsNullOrEmpty(Parameter))
    {
        result = RuntimeManager.StudioSystem.setParameterByID(parameterDescription.id, Value);
        if (result != FMOD.RESULT.OK)
        {
            RuntimeUtils.DebugLogError(string.Format(("[FMOD] StudioGlobalParameterTrigger failed to set parameter {0} : result = {1}"), Parameter, result));
        }
    }
}

```

If there are any updates on the issue I will let you know.
