String values in GetParameterAsText()

Hi,

I have a working ArcMap script tool called Update Map Elements that updates text and numbers in ArcMap documents.

It has four parameters; Workspace, Output, oldText and newText. Workspace is where the input folder goes. Output is the save-to folder. OldText is the text string to be replaced by the newText text string (Red Branch changes to Blue Branch).

My problem is: how can I have multiple string values? So, in the above parameters I specify the Red Branch string value to be replaced by Blue Branch. What if I wanted to have a bunch of string values--such as Red Branch, 600, Violet (oldText) and the corresponding newText values Blue Branch, 800, Green?

I have a feeling I add index positions to the values within the script, but I'm not sure how. I've had a look at this though I'm not sure it's the right approach: SetParameterAsText—Help | ArcGIS for Desktop  

Here's the script behind the Update Map Elements tool:

#set path to relevant folder
import arcpy
from arcpy import env
import os
arcpy.env.overwriteOutput = True

# set path to relvant folder
arcpy.env.workspace = Workspace = arcpy.GetParameterAsText(0)
Output = arcpy.GetParameterAsText(1)
oldText = arcpy.GetParameterAsText(2)
newText = arcpy.GetParameterAsText(3)
# list the mxds of the workspace folder
for mxdname in arcpy.ListFiles("*.mxd"):    
    print mxdname
# set the variable
    mxd = arcpy.mapping.MapDocument(Workspace + "\\" + mxdname)
# replace '2016' that occurs in the title of document
    for elm in arcpy.mapping.ListLayoutElements(mxd, "TEXT_ELEMENT"):
        if oldText in elm.text:
            elm.text = elm.text.replace(oldText, newText)
            print '{} changed'.format(elm.text)
    
    for elm in arcpy.mapping.ListLayoutElements(mxd, ""):
        if oldText in mxd.title:
            mxd.title = elm.text.replace(oldText, newText)
# move the mxd.saveACopy outside of the if loop so a copy is saved even it does not meet the condition of the if loops
    mxd.saveACopy(os.path.join(Output + "\\" + mxdname))
# do not include this delete statement inside the above loop or it will delete the mxd object inside the loop. Make sure to dedent.
del mxd 

Thanks in advance.

Thanks Rebecca. Here it is.

import arcpy
from arcpy import env
import os
arcpy.env.overwriteOutput = True

# set path to relvant folder
arcpy.env.workspace = Workspace = arcpy.GetParameterAsText(0)
Output = arcpy.GetParameterAsText(1)
oldText = arcpy.GetParameterAsText(2)
oldList = oldText.split(', ')
newText = arcpy.GetParameterAsText(3)
newList = newText.split(', ')

# list the mxds of the workspace folder
for mxdname in arcpy.ListFiles("*.mxd"):    
    print mxdname
# set the variable
    mxd = arcpy.mapping.MapDocument(Workspace + "\\" + mxdname)
# replace elements that occur in the map document
    for elm in arcpy.mapping.ListLayoutElements(mxd, "TEXT_ELEMENT"):
        counter = 0
        for text in oldList:
            if text in elm.text:
                elm.text = elm.text.replace(text, newList[counter])
                print '{} changed'.format(elm.text)
                counter = counter + 1
            else:
                counter = counter + 1
    
    for elm in arcpy.mapping.ListLayoutElements(mxd, ""):
