Hi, 
I am trying to create formula to calculate task due date based on few scenerios:
Task due date if call 1 = TODAY, call 2 = TODAY + 24 hours, call 3= TODAY + 48 hours, and
1. if lead owner in EU --> work from Monday til Friday
2. if lead owner in Asia --> work form Tuesday til Saturday

So far I've been trying with this but cant seem to work (logic of weekday: 1-Sunday, 2-Monday, ... 7-Saturday)

IF ({!$Record.Country} = "Europe" || {!$Record.Country} = "UK" &&           {!$Record.Week_Day__c} = 1, TODAY() + 1,                   {!$Record.Week_Day__c}= 7, TODAY() +2), TODAY()

IF {!$Record.Country} = "Asia" && (IF ({!$Record.Week_Day__c} = 2, TODAY() + 1, {!$Record.Week_Day__c}=1, TODAY() +1), TODAY()

Please help :((
