Conditionally Hiding / Unhiding Rows In One Worksheet By Referencing Cell In Different Worksheet

coding a VBA macro for one of my workbooks, in which I need to be able to hide/unhide various rows in one worksheet depending on the value of a cell in a worksheet elsewhere in the workbook. The rows start off hidden by default.

As a simplified example:

Worksheet1 has a cell that has option "Set 1," and "Set 2." Worksheet2 has two sets of rows (say, 20:30 and 40:50) that need to be hidden/unhidden depending on the cell in Worksheet 1. These are hidden to start with!

So if Worksheet1's target cell says "Set 1", then on Worksheet2, rows 20:30 would stay hidden and rows 40:50 would be revealed, and then if the target cell says "Set 2," then on Worksheet 2, rows 40:50 would then be hidden, but rows 20:30 would then be revealed.

I was thinking of using something like this:

Rows("20:30,40:50").EntireRow.Hidden = True
If Target.Address="'Worksheet1'!A1" Then
If Target.Value = "Set 1" Then
Rows("40:50").EntireRow.Hidden = False
Else
Rows("20:30").EntireRow.Hidden = False
End If
End If

I think this might work, but every time I try to run this I get various errors, like not referencing my target cell correctly.
