error when changing record in subform

[Kieran]

I have several subforms in my main form. I view each of these using option buttons and macros changing each subforms visible properties to show only the subform represented by that button.

When i edit a record in one of the subforms then click an option button to go to another subform, this error appears. (pic attatched)

I don't know what to do to stop it....
Please help...

Thanks
Kieran
