Help on dbCreateInst function.

Hi,

I have a list of cells that needs to be instantiated in schematic. I chose to use the function dbCreateInstByMasterName() since the list has the library and the cellname. The problem I am facing is when the number of instance is 2, I can never get the function to put 2 instance of the cell. If I give 2 for x_numInst variable it puts <0:2> number of instances and if I give 1 for the x_numInst variable it instantiate only 1(Its suppose to do <0:1> by it logic) instance and if I give 0 it still instantiates 1 instance. 

Thanks,

Mithun.
