Do **not** use repeat. Use "send in N seconds" to repeat the message. See Cubist's code and our other descriptions.He's right, Ken.
If you can't bring yourself to move to using "send", we can advise concerning "wait" options, but "send" is the way to go.
I'll put at the end of this mail a simple exercise using "send". It may help in understanding about send and you might be able to adapt it to your need.

Here is an example for a flashing light. It is a simplification of one of my first scripts using send. I put this script in a circle graphic:
*************************
-- This is empty if flashing is off.
-- It is the id (for message cancelation) if on.
local flashingID
-- Modify this handler when adapting to other uses
on change
if backgroundColor of me is red then
set backgroundColor of me to green
else
set backgroundColor of me to red
end if
end change
on startFlashing
-- don't start cycle if it is already going
if flashingID is empty then cycle
end startFlashing
on cycle
change
send cycle to me in 333 milliseconds
put the result into flashingID
end cycle
on stopFlashing
cancel flashingID -- don't bother testing for empty
put empty into flashingID
end stopFlashing
****************************
My "Start" button has this script:
******************************
on mouseUp
send startFlashing to graphic "Flasher"
end mouseUp
*******************************
The stop button has this script:
*******************************
on mouseUp
send stopFlashing to graphic "Flasher"
end mouseUp
*******************************
