Updating layer datasource in multiple map documents using ArcPy gives SyntaxError?

Question

I would like to update the data source of a specific layer in multiple map documents using ArcPy.

However, I'm getting a <type 'exceptions.SyntaxError'>: invalid syntax error on if lyr.datasetName == inputlayer in the code below.

import arcpy, string, os
import arcpy.mapping as MAP

try:
    MXDList = string.split(arcpy.GetParameterAsText(0), ";") #ArcMap document(s)
    inputlayer = arcpy.GetParameterAsText(1) # featureclass
    newwork = arcpy.GetParameterAsText(2) # Workspace

    for MXDPath in MXDList:
        MXD = MAP.MapDocument(MXDPath)
        for dataframe in arcpy.mapping.ListDataFrames(MXD):
            lyrs = arcpy.mapping.ListLayers(dataframe)  
            for lyr in lyrs:
                if lyr.datasetName == inputlayer
                    lyr.replaceDataSource(newwork, "FILEGDB_WORKSPACE", "Center")
    MXD.save()

What causes the SyntaxError here?

I was attempting to reference this forum thread.

You're missing a colon. if lyr.datasetName == inputlayer:

Also, the last line MXD.save() should be indented an additional 4 spaces.
