Here is the pattern that all `SWITCH()`

functions follow.

```
SWITCH(
[the value you're trying to test],
[the 1st possible value], [what to insert if the 1st value is true],
[the 2nd possible value], [what to insert if the 2nd value is true],
[the 3rd possible value], [what to insert if the 3rd value is true],
...
[optional, one last 'what to insert' if none of the other values are true]
)
```

To answer yourâ question, â2â is your âthe 2nd possible valueâ, and {Extrachildren}âŚ is the âwhat to insert if the 2nd value is trueâ. If you put the parenthesis comes before â2â, you are grouping both âvalueâ and âwhat to insertâ. Those two need to be separate arguments for this function.

So, walking through your use case, hereâs the structure:

```
SWITCH(
{Qtr},
"1", (insert x1),
"2", (insert x2)
)
```

x1 == `{Extrachildren} * MIN(({Weeks FM} + {WeeksSR}), 10) * 5`

x2 == `{Extrachildren} * MIN(({Weeks FM} + {WeeksSR}), 11) * 3`

Again, you donât have to wrap âx1â or âx2â within parenthesis, but if you did want to, your formula should be:

```
SWITCH(
{Qtr},
"1", ({Extrachildren} * MIN(({Weeks FM} + {WeeksSR}), 10) * 5),
"2", ({Extrachildren} * MIN(({Weeks FM} + {WeeksSR}), 11) * 3)
)
```

If you didnât want the wrapped parenthesis, it would be:

```
SWITCH(
{Qtr},
"1", {Extrachildren} * MIN(({Weeks FM} + {WeeksSR}), 10) * 5,
"2", {Extrachildren} * MIN(({Weeks FM} + {WeeksSR}), 11) * 3
)
```
