Two general “tips” (not directly related to your question):
-
It’s recommended to use
Filter()
instead ofLookup()
, in your case[Table 1].Filter([add this row]=true).First()
instead of[Table1].Lookup([Add this row], true).First()
.
See this thread (answers in post #6 & #7): Filter() vs Lookup() — what’s the difference really? -
Since your filter is based on a checkbox column, you can use
[Table 1].Filter([add this row]).First()
since the value of the[add this row]
column is already true or false.
