not seeing named range when merging named range excel to wor

Ok am a newbie to mail merging but having had suces so far the following has me stumped
I used insert name define to name the ranges on different worksheets in the one xls doc that I was going to need on different word docs. Then when I went to word to do the merging it could not see any of the named ranges. it said entire worksheet only and not even seeing the diffrent worksheets in the xls.
I am using Word and Excell 2000 on a Win ME machine

I wanted to add that having looked at the formula of the named ram\nge it is not putting the ' aound the sheet name. and I cannot seem to edit or add the necessary' to make it see the range'
