Regarding usage of Dependant Value stes

Hi,

While trying to tag a Depandent Value set to a parameter of a Concurrent request below error is coming.

The value set (Dependent value set name) on Segment (Parameter name) cannot be used.

First add and save the Independant value set (Independent value set name) on a previous segment before using the dependent value set (dependent value set name) .

But I have already used the Independent value set in teh previous segment.
