PBM stands for "Partial Body Morph". I think DAZ and others use this as a "dial name" to indicate that the morph is slaved to a FBM channel in the BODY actor. the channel name in your code should be the internal name of the master channel;

                   valueOpDeltaAdd
                                Figure #
                                BodyPartName:#
                                
                        deltaAddDelta 1.000000

The above would corispond to a master channel named "[valueParm] MasterChannelName", where "valueParm" is the channel type and "MasterChannelName" is the channel name. In short, you should not use PBM[ChannelName] unless the master channel is actually called "PBMChannelName", which it probably isn't. I am guessing that you have multiple figures in your document, and I suspect that your problem is one of crosstalk. To test this hypothesis, load the figure with the ERC on its own without any other figures in the document and see if the ERC works then. If this works, then we know that the problem is crosstalk. To find the best solution it would be necessary to have more details than you have provided so far. What exactly are you trying to achive here? Is the code native to the cr2, or is it being injected? Is you figure a conforming figure? If so what figure is it intended to conform to? Do you need to have more than one instance of the figure in a document? Is it necessary for any reason that the name of the master channel be "Muscular1", and if so is a channel named "Muscular1" likly to exist in any other figures in the same document? "Now if I replace it with this code it should not work right?" Figure 15 BODY:15 No, actually it is more likly to work, as the root of the problem (if my assumptions are correct) is Poser's failure to update the actor number in the slaving code correctly. In other words if the figure with the ERC that is not working is the second figure loaded, then the problem may be that this figure is using an actor number of ":2", but the slaving code is still using an actor number of ":1", and thus pointing to a master channel in the first figure loaded, rather than to its own master channel.
