I'm trying to EXTRACT some content from a table to be used for selecting items on a select multiple box.

This works fine:

```
VERSION BUILD=9030808 RECORDER=FX
TAB T=1
URL GOTO=https://www.w3schools.com/tags/tryit.asp?filename=tryhtml_select_multiple
FRAME NAME="iframeResult"
TAG POS=1 TYPE=SELECT FORM=ACTION:/action_page.php ATTR=NAME:cars CONTENT=%volvo:%opel

```

How come that when creating the extract content as a variable, then it does not work:

The variable called `SET CARS volvo:%opel`

```
VERSION BUILD=9030808 RECORDER=FX
TAB T=1
URL GOTO=https://www.w3schools.com/tags/tryit.asp?filename=tryhtml_select_multiple
FRAME NAME="iframeResult"
SET CARS volvo:%opel
TAG POS=1 TYPE=SELECT FORM=ACTION:/action_page.php ATTR=NAME:cars CONTENT=%{{CARS}}

```

Error message:

`Entry [volvo:%opel] not available [Box has 4 entries], line: 6 (Error code: -924)`
