Incompatible units?

Today I struggled with the units package - again...

Let me show you what I did:

	Dynamic[Subscript[\[Tau], p]]
	Subscript[l, case]
	\[Lambda] = \Convert[Subscript[l, case]/Dynamic[Subscript[\[Tau], p]], 1]

This input results in:

	27.4889 Meter Milli
	281 Meter Milli

	Convert::incomp : Incompatible units in (281 Meter Milli)/(27.4889 
Meter Milli) and 1.
	(281 Meter Milli)/(27.4889 Meter Milli)

If I don't use dynamic but constant tau_p everything is fine...
So Mathematica isn't able to to reduce this fraction? What's the reason 
for this behaviour and what can I do about it?

Thanks for your help!
