Get all Properties and update [SOLVED]

I'm trying to create a tag plugin that accesses all properties of an object, list them in the plugin interface, and alter their values with various code multipliers.  I'm able to get the property types, but am unable to update an object property.  Here is what I have so far:

  
for bc, paramid, groupid in description:                 # Iterate over the parameters of the description
    if bc[c4d.DESC_NAME] and bc[c4d.DESC_IDENT] and prop == True:
        theType = bc[c4d.DESC_IDENT]
        theType = str(theType)
        type2 = "c4d." + str(theType)
        doc.SendInfo(c4d.MSG_DOCUMENTINFO_TYPE_LOAD, c4d.FORMAT_C4DIMPORT, "", None, False)
        if bc[c4d.DESC_NAME] == "Size":
            print op[c4d.PRIM_CUBE_LEN]
            print type2
            print op[type2]

The output with the tag on a default cube gives me:
Vector(200, 200, 200)
c4d.PRIM_CUBE_LEN
IndexError: Invalid key type.

Hello,

in your code you store a string in your "type2" variable. Then you use that "type2" variable to access a parameter with "op[type2]". That makes no sense.

GetParameter() or SetParameter(). This means that the ID of the parameter is not defined as a string but as a DescID object. While in many cases it is enough to just use the parameter ID integer value, in some cases a full DescID object has to be used.

You are already looping through the description. While doing so you get the needed parameter ID with "paramid".

Best wishes,
Sebastian

Thanks for the tip Sebastian.  
Using paramID, and some detective work in this forum, I was finally able to get what I wanted.

for bc, paramID, groupid in description:                 # Iterate over the parameters of the description
    if bc[c4d.DESC_NAME] and bc[c4d.DESC_IDENT] and prop == True:
        if bc[c4d.DESC_NAME] == "Size":
id = paramID[0].id print op[id]

This code gives me:
Vector(200, 200, 200)
