T Sql join query

[ish27]

i have a problems in joins. if i run two queries separately it runs fine but if run using joins its creating problem

SELECT 
Div, Bill,  count(CPT)) as [Count(Paid Claims)],sum(ChgAmt)as [Charges Paid($)],sum(PayAmt)as [Payments($)], SUM(PayAmt) / SUM(ChgAmt) as [PMT/CHG(%)] ,sum(PayAmt)/ convert(int,count(CPT)) as [AVG PMT ($)] FROM dbo.PaymentFile group by   Bill, Div order by  Div asc, Bill asc

and second query is

SELECT  
Div, Bill,count(CPT) as [Count(Claims)],sum(ChgAmt)as [Charges($)]
FROM dbo.TransactionFile group by   Bill, Div order by  Div asc, Bill asc

and if i join this query like this

SELECT  
t.Div, t.Bill, (t.CPT)) as [Count(Claims)], sum(t.ChgAmt)as [Charges($)],
p.Div, p.Bill, (p.CPT))as [Count(Paid Claims)],sum(p.ChgAmt)as [Charges Paid($)],
sum(p.PayAmt)as [Payments($)],(p.CPT))/(t.CPT)) as [Claims(Paid %)],
sum(p.PayAmt)/sum(p.ChgAmt)as [PMT/CHG(%)],
sum(p.PayAmt)/count(p.CPT) as [AVG PMT ($)]
FROM dbo.TransactionFileas t,dbo.PaymentFile as p
group by   t.Bill, t.Div,  p.Bill, p.Div
order by  t.Div asc, t.Bill asc

its taking more than an hour to execute and

i was also getting error in conversion failed when converting the varchar value to data type int

bcoz cpt column is varchar but when i run separately no error occurs

please help me out

thanks in advance
