Hello All, I'm having an issue with the Using Formula Field Challenge . I'm using the formula that Vivek provided to a solved question yesterday " TODAY()  -    DATEVALUE(LastModifiedDate) " but its been met with this error below when its been checked by the challenge " 

Challenge not yet complete... here's what's wrong: 
The 'Days_Since_Last_Update__c' formula field did not return the correct number of days between an Account’s Last Activity Date and today

Can anyone assist???

We're having trouble with the "Extending Reports using the AppExchange" module in Trailhead

We keep getting the same error when checking the challenge at the end of the module:

Challenge not yet complete... here's what's wrong: 
The 'LEAD Trend by Source' dashboard component does not have the wedges set to 'Lead Source'.

Wedges ARE set to 'Lead Source', did anybody get this error message? do you know what the solution may be? Thank you!
