Taxes calculation

When setting my calculation type for tax can i use the same account transaction types that i have used in setting up my tax template or do i have to replicate some new account transactions to deal with tax calculation. please find my attached template below.

This is my Tax Template

This is what am getting while trying to set up myTax calcutation type

The question is why is that the account transaction dealing with tax calculation types cannot be used by the tax template as shown above.

That account transaction has a tax template already assigned by. Try create a new account transaction type and assign it to that calculation. It should work then .

thankyou it has worked perfectly
