Just to check, this is what you should have done...
Open the Pages file you want to convert. Save to Word format in Pages.
Go to the “File” menu and choose “Export To”, then select “Word” from the sub-menu.
In the “Export Your Document” screen under the ‘Word’ tab, click the triangle next to ‘Advanced Options’
Select a format - docx for instance, if you want the file to be compatible with later Woird version.
Give the Word file a name and select a destination to save the file to. Then choose “Export”.
That's it. Not every file will convert perfectly - try to avoid using fancy fonts, and keep the formatting features simple. With a bit of trial and error you'll get it to work perfectly.
