ulc | Untyped Lambda Calculus REPL written in Swift | Interpreter library

I have a sheet where I need to limit the number of checkboxes allowed within a range. Like this

H219 to H225 allows only one checkbox to be checked.

H228: H335 allows three checkboxes.

H340:H347 Allows two checkboxes.

This script works when I use it once, but when i add it multiple times and change the range it seems to stop working.

When a row is selected in ULC but it doesn't have focus (i.e selecting a row, then opening a dialog) the colour scheme of the highlighted row, light grey text with a slightly darker background is rather difficult to read. How can I darken the text in this circumstance? Thanks.

I have looked long and hard at the ULC demo, and it is rather complicated. Can someone please show me how to add an image to each of the rows? Thanks.

Goal: I'm struggling with an expression (.NET) that can capture just the Full Description Column by itself and a separate expression that can pull just the Net total column. I know both can be captured in one expression but I need to separate expressions capturing each column

My Regex For The Description Column:

Goal: Trying to capture just Invoice # Column values. My goal was to use the Date to the right of the invoice number to capture the invoice number on the left.

Issue: The formatting of string we are working with has rolled up the last line of the details on to the line before it. See DM20052921 I'm not able to grab (DM20052921) and also getting an unwanted line at the bottom and the top with my regex?

My Regex: ([A-Z\d]+).+(?= 20\d{2}-)

Looking for help on correct Regex Code to pull Invoice #, Date, Description, Gross Disc, & Net in separate groups.

Having difficulty finding pattern on the Description Column.

Sample of how far I got with my code is below also:

I generate a nuget package using my nuspec file below:

So i have a ultimatelistctrl that looks like this:

This is how my programm looks like

I want to have darker blue borders on the left and right side of the Window. Despite setting the size manually, for some reason, the top level panel "panel" is resized to the toplevelsizer size. And I don't know why. The way I achieve the other borders is by having a blue panel below the top-sizer and adding spacer between the other panels/widgets.
