**Error** from the compiler, while it builds your `.tsrx` files.

## What happened

Markless prints the message, the reason, and a suggestion:

```text
MARKLESS_SEED_CHILDREN_UNAVAILABLE: <<componentName>> seeds "<statePath>" from its children, but the children written here contain a value that is worked out while they render, so the seed would read nothing.
Shared state is seeded before the projected children render, because those children render from what the seed wrote. Only children the consumer passes as a prop, and children the compiler already spells in full - text, or markup with no expression in it - are known that early.
Write the value as a prop (children={...}), or put text between the tags with no expression in it, or move the write into an event handler where the shared instance is already live.

```

Words in angle brackets change from case to case.

## How to fix it

Start with the suggestion in the message above.
