AND/OR search form with Lasso

[pdbe]

I have a search form which I want to return records with any (OR) of the selected sections AND the specified unit

Where and how can I enter the -OpBegin and -OpEnd tags? I've used the {brackets} to give an idea of what it needs to do:

[inline: Action_Params, -Database='dioexp', -Table='Web', -KeyField='', -Show]

{BEGIN AND}

{BEGIN OR}

[Value_List: 'section']

[if: (Action_Param: 'section text') >> Value_ListItem]

[Value_ListItem]

[Else]

[Value_ListItem]

[/if]

[/Value_List]

{END OR}

{END AND}

[/inline]

[/form]

Thanks for your help!
