Rb to filemaker 5 query

I am trying to query my filemaker 5 database. The database is called testdb. The plug-ins for Local data access comp and remote data acces comp are checked. My fields in my database are as so

ID_NUM NAME LAST COMPANY DATE MISC

dim cursor as databasecursor

cursor=testdb.sqlselect ("select * from tempdb where ID_NUM='"+editfield1+"'")

If cursor <> nil then

editfield2.text=cursor.field("NAME").getstring

editfield3.text=cursor.field("LAST").getstring

editfield4.text=cursor.field("COMPANY").getstring

else

msgbox "Record not found"

end if

What's wrong with the code It is written in Realbasic 5. I want to use rb with a filemaker database. I am entering an Id num into a editfield

and hitting a pushbutton. I am just trying to query the database with the info in editfield1 and getting the results in the other editfields. Can someone please check the code and tell me what I am doing wrong. Thank you in advance
