249: Mix of mutually exclusive and non-exclusive options

Mutually exclusive options are marked by an apostrophe after curly brackets {…}' at the beginning of a line. There can be an unlimited number of mutually exclusive options inside one block and they may be combined with a single preselected option marked by a hyphen after curly brackets {…}-.

But mutually exclusive options can be neither combined with multiple preselected options nor with other options marked by {…}!, {…}1, {…}0 or simply {…} in the same block. This rule is violated in your case.

Solution

Make sure that all your mutually exclusive options are marked with an apostrophe right after the right curly bracket.

If you need a set of mutually exclusive options, but also other options in the same form, then put them into separate blocks with a blank line in between. Here is an example:

Choose a size for your shirt:
{s}' small
{m}' medium
{l}' large

{TOS}! I have read and accept the terms of service.

Leave the apostrophe away, if your options are not mutually exclusive like in the following example:

What are you going to wear tonight?
{d} a dress
{s} shoes
{n} a necklace
