Since you were not very specific in your problem description I started
with the most obvious error.
It might be sufficcient to add a ';' to the line before "jmolscript...",
but I would reference the value of your input field in a different way:
var x = document.getElementById("eingabe").value;
This would require also to change the "input" tag definition to
<input type="text" id="eingabe">
If this doesn't help it would be best if you could provide an URL with
the complete example page.

Rolf
