Roger:
Use EditInPlace::YourVariable.TakeEvent. It's a little tricky because
you have to update() the variable here is some sample code out of my
ForKeeps archive. If you ever have trouble finding an old message,
ForKeeps is for you! A quick search on Edit in place found:

>> (CW4B ABC) I have a form with a listbox that uses edit in place. I
want to modify one of the fields in the record based on other fields in
the record and form before the record is saved. Can someone tell me how
to put embed code right before the record is written to disk on an edit
in place listbox? <<
In one case I had two fields, an inventory level and the delta or
change in inventory level from the previous inventory. The general
idea was when one was entered using EIP the other was calculated and
displayed plus some colors where set for the browse line. Here is the
embed for the delta EIP field:
the key features are the events and doing the update(focus()) then just
do what every you want to the browse queue variables and save the Q.
EditInPlace::Loc:Delta.TakeEvent PROCEDURE(UNSIGNED Event)
ReturnValue BYTE,AUTO

then
Update(focus())
loc:delta=brw1.q.Loc:delta !Update local variable
if loc:delta<>0 then
Loc:newQty=loc:curQty+loc:delta
else
loc:newQty=0
end
brw1.q.loc:NewQty=loc:NewQty !update q variable
If loc:delta or loc:newQty then
brw1.Q.ite:ITEMN_NormalFG=color:red
brw1.Q.ite:ITEMN_SelectedFG=color:red
else
brw1.Q.ite:ITEMN_NormalFG=color:none
brw1.Q.ite:ITEMN_SelectedFG=color:None
end
put(brw1.q)
end
! End of "Edit-In-Place Manager Executable Code Section"
RETURN ReturnValue
