Global variable unavailable to sub-form

[GraeagleBill]

I have a general module that Dim's a variable Global. I have a main form and several sub-forms. The main form sets the value of the global variable in its Open Event. However, when the sub-form(s) open the value of the global variable is zero. When I close the main form and then open it again the global variable has the correct value and all the sub-form(s) populate accordingly. What might be the best coarse of action to correct the situation?

Sub forms load before their master form loads so by the time you set the value of the variable in the main forms open event the sub forms open event has already happened.

Thanks Bob, that was my suspicion to begin with. Before I posted, I had tried to put a general module in "front" of the main form, set the variable and then open the main form. The problem there was that in my haste I failed to set Options to Explicit and the general module failed without notice leading me to believe that there were bigger problems with the global variable.

The problem has been easily resolved by putting a small function in "front" of the main form, that is triggered by an Autoexec macro, that sets the global variable and opens the main form.

Thanks again,
Bill
