Guys i am having a problem when trying to convert the poly to sub'd - for some reason it wont work and i dont understand what the error is,

As below:

deleteInternalValence2Verts |polySurface22|polySurfaceShape29;
polyToSubdiv -ap 0 -ch off -aut on -maxPolyCount 1800 -maxEdgesPerVert 32 |polySurface22|polySurfaceShape29;
// Warning: Nothing is selected. Select objects or components to delete. //
// Error: 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[3219] ;string $v[] = `polyListComponentConversion -fe -tv`;select $v;polySplitVertex;polyMergeVertex -d 0.0 -tx 1; //
// Error: Command polyToSubdiv failed. Open Script Editor for details. //

I have selected the object in this case the tree frog - i have tried to do a cleanup just incase there are any problems there but that brings no problems up, is there something stupid i am doing?

Cheers
