Delay Form_Current() ?

Is it possible to delay the Form_Current event? I use the code below to duplicate records, ask for a change in teh reference number and then resort the database according to the reference numbers. This works fine until I introduce some code into a Form_Current procedure. Now whenever I activate the macro below to copy a record the data in the copy record is wiped out and the form rendered with its defaul values. I am assuming this is because the code in the Form_Current section is rendering the form whilst something else is trying to paste values in it so is ther a way to delay either the pasting of the new data or the activation of the Form_Current procedure?

I have tried using a few basic counters but to no avail! Any help would be greatly appreciatted.

Cheers
