I am trying to click "Request roll" so that raid members start rolling on an item. However it is giving me an error as follow:

3x XLoot_Master/Master.lua:154: attempt to call global 'DoMasterLootRoll' (a nil value) [string "@XLoot_Master/Master.lua"]:154: in function func'
[string "@FrameXML/UIDropDownMenu.lua"]:968: in function `UIDropDownMenuButton_OnClick'
[string "*UIDropDownMenuTemplates.xml:149_OnClick"]:1: in function <[string "*UIDropDownMenuTemplates.xml:149_OnClick"]:1>

Locals:
frame = DropDownList2Button1 {
0 =
Highlight = DropDownList2Button1Highlight {
}
notCheckable = 1
func = defined @XLoot_Master/Master.lua:153
icon = "Interface\Buttons\UI-GroupLoot-Dice-Up"
value = 1
Icon = DropDownList2Button1Icon {
}
invisibleButton = DropDownList2Button1InvisibleButton {
}
}
(*temporary) = nil
(*temporary) = 1
(*temporary) = "attempt to call global 'DoMasterLootRoll' (a nil value)"
`

I don't know anything about or have access to SoD. I assume it's running on a newer UI base and thus master looting has been changed since XLoot Master was last maintained.

I welcome pull requests with fixes, but am unlikely to get to it myself.
