Yep for future refrerence, the reason the erc slaved in poser was becouse there were no figure numbers in the erc code. Poser tacks on figure numbers when saving a figure with erc so the code would look like this.

Figure:1

the number would be different depending on how many figures are loaded into the scene before the clothing is loaded. the :1 is there to help prevent crosstalk. if you take the numbers out like you have in your erc than Poser for some reason automatically puts in the number of the figure that is selected when you load your conformer. and you have forced crosstalk. (studio on the other hand ignores the number altogether and automatically slaves all channels that have the same name on the conformer and the base figure)
