Google-sheets – add +1 to year within a text formula

This can be solved by introducting a separate sheet, let's call it 'Weekdays':

| Weekday | Number of stylists Site 1 | Number of stylists Site 2 | Number of stylists Site 3 |
|       1 |                         0 |                         0 |                         0 |
|       2 |                         0 |                         0 |                         0 |
|       3 |                         5 |                         3 |                         5 |
|       4 |                         4 |                         4 |                         4 |
...

The first column is the weekday (0 is Sunday, 1 is Monday, etc), the next columns are the number of stylists available on that weekday, on the different sites.

Having this table, I can use a formula to match a weekday + a site with a number of stylists, from the main sheet. The following formula is for Tuesdays on Site 1:

=VLOOKUP(B$2, Weekdays!$A$2:$D$8,2)

The VLOOKUP function (check out its documentation) takes the value from B2 (Tue, which translates to 2), and matches it against the first column in the Weekdays sheet. When it finds a matching row, it returns the 2^nd column - which is the Number of stylists Site 1.

Thus, the formula can be dragged across the entire row for Site 1, and it will adjust automatically.

For the other sites, you need to modify the last parameter of the formula. For Site 2, replace 2 with 3: =VLOOKUP(B$2, Weekdays!$A$2:$D$8,3), and for Site 3, replace with 4: =VLOOKUP(B$2, Weekdays!$A$2:$D$8,4)

I have set up an example spreadsheet to demonstrate this, feel free to copy it.

• instead of SUM use SUMPRODUCT

  =SUMPRODUCT(C:C)
