Varient Configuration

Hi All,

I have created some, say CHAR1 n CHAR2 n CHAR3 characteristics and assigned them to the class of type 300.

I have assigned this class to a configurable material.

Now what I want is to check if the CHAR2 and CHAR3 are not initial.

And concatenate then into CHAR1 with Hyphen.

Can someone tell me the syntax for that.

Help needed urgently.

Thanks,

Supriya Manik.
