My script editor says:

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[802] ;string $v[] = `polyListComponentConversion -fe -tv`;select $v;polySplitVertex;polyMergeVertex -d 0.0 -tx 1; //

How do i find my duplicate edges? And how do i issue that command? Someone help?
