So I came up with an inelegant solution that solves the problem. To clarify the situation I had, I had a list of tiddlers that would only show five at a time, and would scroll using a range widget and a left/right button combination. The range widget scrolls by 1, the left/right buttons scroll by five. The issue I had was the list and buttons were working correctly, but the range widget was not updating according to the input of the buttons.
The first solution I had was to move the field being modified to another tiddler, which I called Scratch_Pad. This did not work, but it was convenient for me for later on. Second solution I had was to change the default value of the range widget to equal Scratch_Pad!!scroll_index, which is the same value the widget and the buttons modified. It worked, but the slider was very difficult to use as it would de-select itself every time I moved the slider, requiring me to re-click the slider and move it one-by-one every time I wanted to change the value. The solution that finally worked is a bit wonky. I read in another thread that modifying a draft of a tiddler works smoothly for the range widget. The problem I had was having the default value of the range widget be the same field as the value the range widget was trying to modify. Here's what I did instead: Set the tiddler the range widget modifies to be Draft of 'Scratch_Pad', keeping the field as scroll_index Set the default it pulls from to be Scratch_Pad!!scroll_index, NOT the draft Set the value the buttons base their calculations on to Draft of 'Scratch_Pad'!!scroll_index. This makes sure the buttons will move the value last updated by the range widget. When the buttons calculate the new values, make sure they update the scroll_index fields in both the Scratch_Pad AND Draft of 'Scratch_Pad' tiddlers to update the range widget's position and make sure the value it next calculates is accurate Base the horizontal list's position on the Draft of 'Scratch_Pad' value.
