AddHandler Type mismatch error

General
1

I’ve used this code before but can’t seem to get it work in another web app today. I see no difference between the two apps.

property: pTIMER_cleanup As Timer

Opening Event of a WebApp:

pTIMER_cleanup = New Timer
pTIMER_cleanup.Enabled = True
pTIMER_cleanup.Period = 3000
pTIMER_cleanup.RunMode = Timer.RunModes.Multiple
AddHandler pTIMER_cleanup.Action, AddressOf m_0_cleanup

AddHandler gets error messages:
Type mismatch error. Expected delegate Delegate( Timer ), but got delegate Delegate( )
AddHandler pTIMER_cleanup.Action, AddressOf m_0_cleanup

This method requires fewer parameters than were passed
AddHandler pTIMER_cleanup.Action, AddressOf m_0_cleanup

XOJO versio 20201r2.1

The first parameter of m_0_cleanup should be a Timer.

I must have looked at the fifty times. Thanks.
