Hi,
you need to built up the string for passing arguments to the plugin.
SizeE is a number not a string.
code should be like:

int sizeE = 2; //sizeE is asked before since I don't want to call the plug-in I'm re-using itself
IJ.run(imp2, "Gray Morphology", "radius=" + sizeE + "type=circle operator=erode");

hope this helps,
Rob
