Calling function with parameter from out of WITH....ENDWITH construct

I place an image in a contrainer on a form. The image contains an outline map of a country and on this image map I place weather stations as images (small coloured squares). These can be a few hundres. When double clicking on a station I need to run a
function that does a few things....

The country map and weather stations are placed after opening the form, dependiong on the country selected by the user. The solution to running a function applicable to all stations, seems to be to place the function outside the CLASS ... ENDCLASS constr
uct and have it called by a leftDblClick event for whatever station the user is interested in.

In the WITH...ENDWITH construct of the weather station a

onLeftDblClick = alter(mstationno)

is inserted. The problem is that when calling the function without the parameter, it works. However, inserting the parameter (a station identifier) leads to different reactions:

1. Error message telling me that a function is required (the function definition includes a handle to which the parameter can be passed)

or

2. It calls the function and runs through it(!).

Event 1 above is the more common occurance. Event 2 happens about once in ten.

Can someone please put me on the right track?

And thanks to all who responds to our requests.

Perhaps something like the following will work for you:

function onLeftDblClick(flags
, col, row)
form.alter(mstationno)
return

function alter(mstationno)
?mstationno
return
