Pass Variable to LayerDefinition Flex 1.3

[BryanWestphal]

Im having trouble passing a string Variable to the Dynamic Map service. 

any ideas would be very helpful.

Thanks in advance

I should probably add in that I want to set that variable as the layer definition for that specific layer.

sorry for any confusion.

Thanks in advance
