cSavepath not saving based on if then statements

HI,

I am trying to make it so if the total number of pages (numPages) is 1, then the code inserts the "1" +  "page" and if there is a total of 3 pages , it would insert save as "3" + "pages".  I don't understand why the following is not saving the pdf with the cSavePath (i.e., filename) based on whether the total # of pages is 1 or not 1:

        cSavePath += " - "

        cSavePath += event.target.numPages

        If (event.target.numPages == "1")

       {cSavePath += " page"}

        If (event.target.numPages != "1")

        {cSavePath += " pages"}

I even tried as numerical value:

cSavePath += " - "

        cSavePath += event.target.numPages

        If (event.target.numPages = 1)

       {cSavePath += " page"}

        If (event.target.numPages > 1)

        {cSavePath += " pages"}
