Global variable

Hi,
I will explain my problem in short. I make a window form application and add 3 buttons. When a press button 1. I want to create 8 or 16 or 32 combobox and i make this with follow code:
private: System::Void button1_Click(System::Object^ sender, System::EventArgs^ e) {
golfunctions=32;
array^ pcom = gcnew array(golfunctions);

Code:

			
			 	x=28; y=106; j=0;
			 for(i=0;iSuspendLayout();			
				pcom[i]->FormattingEnabled = true;
				pcom[i]->Items->AddRange(gcnew cli::array< System::Object^  >(3) {L"0", L"1", L"x"});
				pcom[i]->Location = System::Drawing::Point(x, (y+20));
				pcom[i]->Size = System::Drawing::Size(35, 20);
				pcom[i]->TabIndex = 36;
	
			Controls->Add(pcom[i]);
		

				x+=35;
				if((i==15)&&(j==0))
				{
					x=28;
					j++;
					y+=40;
				}
			
				
				
			}

This work fine! After that i want to take the choosen value ot each combobox when i press button 2 but
private: System::Void Add_Click(System::Object^ sender, System::EventArgs^ e) {


for(i=0;iSelectedItem);
.....
//if(pcom->SelectedItem

}
}
i compile program and work to the moment when i press button 2 and
show error. i start the program in debbuge mode: at row
temp=System::Convert::ToChar(pcom->SelectedItem);
show -pcom
pcom error: index 'i' out of bound for pointer/array 'pcom'
My supposition it that i make pcom local variable and can`t use in range of button2
any i ideas who to make that ot how to find decision of this problem
