I'm trying to create a conditional format that will highlight a cell if
two conditions are met one of which is that the cell is found within a
dynamic range.

Is there a function or formula I could use to determine if, say, cell
B1 is within the range A1:D1? If so, I could use a conditional format
like the following:

= AND(B1=Min(E1:E5), B1 is in the Range A1:D1)

It may look funny but there are certain times that the range will
change from A1:D1 to C1 or B1 based on the data entered elsewhere in
the table.

Thanks.
