MyXl is declared in cmdOpen_Click and should be passed to Variables, otherwise it will be undefined.

public void Variables(Excel.Application MyXl)

Also, about the next line:

object ws;

Use specific type declaration for other excel classes like workbooks and worksheets:

Excel.Workbook wb;
Excel.Worksheet ws;

Good luck!
