Need SQL Case Statement Help

When using the following case statement I get results that = "Total Records" for the year in all monthly columns.
Please see attached results spreadsheet as example of query results.
I do not understand what the problem is.

If I change "count" to "sum" I get the following error-
Msg 245, Level 16, State 1, Line 1
Conversion failed when converting the varchar value 'sourcefrom' to data type int.

begindate = datetime
sourcerfrom = varchar(20)

select datepart(year,begindate) as Years,sourcerfrom,
count(case when datepart(month,begindate)= 1 then sourcerfrom else 0 end) as January,
count(case when datepart(month,begindate)= 2 then sourcerfrom else 0 end) as February,
count(case when datepart(month,begindate)= 3 then sourcerfrom else 0 end) as March,
count(case when datepart(month,begindate)= 4 then sourcerfrom else 0 end) as April,
count(case when datepart(month,begindate)= 5 then sourcerfrom else 0 end) as May,
count(case when datepart(month,begindate)= 6 then sourcerfrom else 0 end) as June,
count(case when datepart(month,begindate)= 7 then sourcerfrom else 0 end) as July,
count(case when datepart(month,begindate)= 8 then sourcerfrom else 0 end) as August,

count(case when datepart(month,begindate)= 11 then sourcerfrom else 0 end) as November,
count(case when datepart(month,begindate)= 12 then sourcerfrom else 0 end) as December,
