Hello, I'm trying to add a sheet within a sheet. I have 3 bank accounts, account 1 is sheet 1, sheet 2 is account 2, sheet 3 is account 3. I need to create sheets or sub sheets that I can create so when I click the sheet, my sub sheets pop up so I can then select the sub sheet I want. In this case the subsheets I want to create are for each month. So when I click the sheet for "account 1" I need to then be able to click "October" to view my current account, or maybe click "September" to view my last months activity for that specific account. These are business account and they're all for the same business, the accounts are linked together and I am often making transactions with all the accounts in all different ways and I'm also often transferring money from one account to the other. That's why I need this all together in one instead of creating a while different spreadsheet for each account. Help me please????? And thank you very much in advance.
