Access - field names -- variable

[kfcSmitty]

On my table i have fields like

WorkerID
Course1
SD1 (startDate1)
ED1 (enddate1)
Course2
SD2
ED2

all the way to 15.


Now I want to store certain dates into this..so I have been trying to enter the data into the fields with this

dim intcounter as integer
do while rssstorage.eof = false
      intcounter = intcounter + 1
      fieldnames = "SD" & intcounter
      RsStorage.Fields(fieldnames) = Date
loop

But that doesnt work...For the record thats not a copy, i just wrote it out now..but its basically what i am trying to do
