vb.net - Else statement not reaching the correct If for error -

i'm having problem because have combo box converted dropdownlist box , if not choose server inside of server not let them log in. i've put else statement when don't choose server correctly it'll pop up. want program use correct if statement kind of error.

code: (entire code)

 if txtusername.text = my.settings.username , txtpassword.text = my.settings.password , cmbservers.text = "redox server"             stripstatus.text = "connecting 'redox server; please wait...'"             frmredox.show()             me.close()          else             if txtusername.text = "" , txtpassword.text = ""                 msgbox("please input username , password login. if not have account may create one.", msgboxstyle.exclamation, "redox - error")             if cmbservers.text = ""                 msgbox("please select server called 'redox server'.", msgboxstyle.critical, "redox - server connectivity error")              end if         end if     end if 

you did @ least miss "endif" or "elseif".

else     if ...         dosomething     endif     if ...         dosomething     endif endif 

or this:

else     if ...         dosomething     elseif ...         dosomething     endif endif
