I am having trouble converting a poly mesh to sub division. I think the problem may be that one of the legs of my model has a funny attachment to the body of the character. When the booleans operation didnt work, i cut out faces using the split poly tool, and combined the leg with the body, merging the verts as I went around. I had border edges on thick display, and as i went the se edges thineed out as the two objects became one, but there is one last thick border edge I cant get rid of. The poly to sub d operation failed and told me to open the script editor, which has told me the following:

polyToSubdiv1 (Poly To Subdiv Node): The conversion to a subdivision surface failed.
// One or more duplicated edges were present.
// Repair the duplicate edges by selecting the polygon
// and issuing the following command, then try again:
select .e[2662] ;string $v[] = `polyListComponentConversion -fe -tv`;select $v;polySplitVertex;polyMergeVertex -d 0.0 -tx 1; //
mand:


Do i issue this somehow in the script editor? What do I have to have selected in the workspace/on the model if so. Otherwise can anyone see from this what I can do?
