Welcome to the community, @Adam_Nicoloff! :grinning_face_with_big_eyes: This can be done using links between the two tables, plus a lookup of the stage from the [Order Numbers]
table.
Long story short: in [Table 1]
(you referred to this as “Sheet 1” and “Base 1” in different places, but it sounds like you’re describing a table, so that what I’m calling it) your {Order Number}
field should be a link field that lets you choose a record from the [Order Numbers]
table. Only one link per record pointing to a single order number record from the other table.
In the [Order Numbers]
table, you have a {Stage}
field of some type. With the link between [Table 1]
and [Order Numbers]
, you can look up values between them. In this case, you’d add a lookup field to [Table 1]
that shows you the stage of the order, using the link that you made in the {Order Number}
to a specific order from the [Order Numbers]
table. When you change the stage in [Order Numbers]
for a given record, any records in [Table 1]
that link to that order will reflect that stage change.
