            Positioning a line with text between two divs
            Asked 2021-Jun-15 at 09:40

            I've been redesigning a calculator for my website and there's a feature that I'd like to add to it. I have two divs next to each other and another div that I'd like to put in between them. I've been using the float function but nothing obvious seems to work. Aside from that, the div is supposed to contain two lines over and under text (I'll elaborate a bit more later) and I'm not sure what to do to achieve this, can someone please help?

            Below is an image of what my issue is (red boxes are just to show the divs).

            Below is what I'm trying to achieve (red boxes are just showing each div - not actually part of the design). I want a line above and below "OR" that separates the divs on either side and it has to resize relative to the size of the whole thing. For example: if the window is resized (if that makes sense).

            If you need additional information then please ask.

            I wouldn't recommend you to use float since it has a strange behaviour sometimes. I would rather use flexboxes to achieve the layout.

So, I want the sum of the G column, the sum of the M column, and so on, but only if the column value is greater than 0. The sums are then assigned to consecutive cells in a sheet called 'Calculator.'

            First, I believe you mean var total = (com + subject) * n_q; rather than var total = (com + subject)n_q;.

            Second, all if clauses run the same code, so you can remove all the if statements and leave the code as.

            Third, you need to change getElementsById to getElementById.

            How to limit options based on a based on another , without changing values
            Asked 2021-Jun-14 at 02:05

            I have two selects, I want to configure them so that only a certain amount of options show in the second select, depending on which first selection is chosen.

            I found some code from this post and I've tried to edit it for my situation, as I need too keep the values as they are, because I'm using them in a calculator that needs them like that.

            If any one could help me fix/finish this code so it works, it would be much appreciated!

            What I'm trying to achieve:

            • If the user selects combo-x1, bench-x1 option only shows
            • If the user selects combo-x2, bench-x1 option + bench-x2 option only shows
            • If the user selects combo-x3, bench-x1 option + bench-x2 + bench-x3 option only shows
            • If the user selects combo-x4 up to combo-8, all options show

            With dart null safety you cannot assign null to the String opp;

            The error says you have initialized the variable opp; with null value. To avoid that either,

            1. change String opp; to String? opp;

            2. use late keyword before opp as late String opp; (in this case you have to make sure that you are assigning opp variable before is is used otherwise it will throw late initialization error again)

            3. assign value to opp variable at the declaration as String opp = "someString";
