your open form code
Code:
DoCmd.OpenForm "frmOrderReportButtons", acNormal, "", "", , acNormal
has an incorrect window mode argument. it should be acWindowNormal
Code:
DoCmd.OpenForm "frmOrderReportButtons", acNormal, "", "", , acWindowNormal
Since you dont have any filter or where criteria and you are using the defaults for all the optional arguments you only need
Code:
DoCmd.OpenForm "frmOrderReportButtons"
No need to use "" as a placeholder for optional arguments.
edit: Just noticed Gasman mentioned acWindowNormal. oops.
