Multiple Fields in a variable count

[Anonymous]

So I have a variable count that goes:

=count(if([Material Description]='3S',WorkNotification))

How can I write this to add multiple Material Descriptions instead of just one. I have 5 that I want to include in this count.

Please help,

Thanks.

count(if (Match([Material Description], '3S',WorkNotification')).. you can add as many Material Descriptions as you want.

Thanks

replace material descr

count({$ <[Material Description]={'3S','4S','5S','6S','7S'}>}  WorkNotification)

You can use Wildmatch as well

The difference is that you can use '?' & '*' to look for values that are closer to your search value
