Hi Helen,

Thanks for using Sage City :)

I notice this query has slipped through without a community response, sorry for the late reply but I thought I’d pop something back to you :)

The 'include for holiday accrual' box sets whether a pay element is included in the calculation for Holiday fund accrual. 
The "Include for weekly averages" box sets whether a pay element is included in the calculation of 12 week, 13 week and 52 week averages.

Whether or not they should be ticked would depend on your needs so I'm afraid I couldn't advise as to whether they should be ticked or not.
A great resource for what the options mean on the pay element setup is our help centre page on this, to access it quickly you can press the F1 key on your keyboard while in Company>Pay elements and this page will load for you. Also, pressing F1 in any area of the program will open a support page relevant to that area too
