[Lua Error] Attempt to index field 'scrollFrame'

[F-Lambda]

Getting the following Lua error:

Message: [string "OnlineFrameSlider:OnValueChanged"]:1: attempt to index field 'scrollFrame' (a nil value)
Time: 10/13/24 21:43:34
Count: 1
Stack: [string "*:OnValueChanged"]:1: in function <[string "*:OnValueChanged"]:1>

Locals: self = OnlineFrameSlider {
 0 = <userdata>
}
value = 0
(*temporary) = nil
(*temporary) = nil
(*temporary) = nil
(*temporary) = nil
(*temporary) = "attempt to index field 'scrollFrame' (a nil value)"

The error seems to be in OnlineFrame.xml, line 249:

			<Scripts>
				<OnLoad>
					OnlineFrame.slider = self;
				</OnLoad>
				<OnValueChanged>
					OnlineFrame.scrollFrame:SetVerticalScroll(self:GetValue());
				</OnValueChanged>
			</Scripts>

I solve it with :

<OnValueChanged>
          if (OnlineFrame.scrollFrame ~= nil) then
            OnlineFrame.scrollFrame:SetVerticalScroll(self:GetValue());
          end
</OnValueChanged>

Also got similar message in StrategyFrame.xml so did same medicine in that file:

<Scripts>
	<OnValueChanged>
	       if (self.scrollFrame ~= nil) then
	           self.scrollFrame:SetVerticalScroll(self:GetValue());
	       end
	</OnValueChanged>
</Scripts>
