The Excel versions have changed over the years as have filemaker. It's possible that the excel file generated by Filemaker 11 is not compatible with Filemaker 3.
Try exporting the data as a tab or comma separated (.csv) file and import the data from it using Import records. (You'll have to create a table in Filemaker 3 to recieve the data first).
Thanks that helped but heres a question,, i was earlier working on file maker pro 11 and it allowed me to send emails to contacts, can you do that on file maker pro 3.0?
I don't believe you can with filemaker 3.0. If memory serves (you're using a very old version of filemaker here), it wasn't until filemaker 4 or 5 came out that you had any email capability at all.
