* Note that sometimes the result of the formula may give 0 (arithmetically) and therefore the trade should be accepted but it is not. This is because of floating-point errors. The handling of these errors can be done but that would over complicate the representation of the formula on this page. | * Note that sometimes the result of the formula may give 0 (arithmetically) and therefore the trade should be accepted but it is not.

To change the slider position through script, use [[SetMenuFloatValue]] with the default path for the slider value being; "Negotiate_Background\Negotiate_Scroll\Horizontal_Scroll_Marker\_Value_Scrolled_To". | |||
Example: SetMenuFloatValue "Negotiate_Background\Negotiate_Scroll\Horizontal_Scroll_Marker\_Value_Scrolled_To" 1025 SliderPositionVar | |||
