Aris 7.1 - Script issue

hello,

I want to copy attributes from one model to another and here is the below code which aint working.

Can somebody correct this or let me knw if this is correct?

I have created a seperate function to copy model attributes from source model to target model.

function copyAttributes(osourcemodel, oTargetModel)
{
 
        var oAttrList = osourcemodel.AttrList(g_nLoc);
        // Copy attributes
        for (var j = 0 ; j < oAttrList.length ; j++ )
        {
            var oAttr = oAttrList[j];
            if (oAttr.TypeNum() != Constants.AT_NAME_LGINDEP)
            {

                var oNewAttr = oTargetModel.Attribute(oAttr.TypeNum(),g_nLoc);
                if (oNewAttr="")
                {
                    oNewAttr.setValue(true);

}
