hi can u help me in converting this PDL into flow chart :

sum = 0
If Condition1 or not Condition2 then
	for i = n1 to n2
If not Condition3 and Condition4 then
			for j = n1 to n2
				Body1
Else
			for j = n1 to n2
				Body2
return sum

Set the sum value to zero
Get Condition 1 Value
Get Condition 2 Value
Determine the value for nl and n2
Get Condition 3 Value
Get condition 4 Value
Body1????
Body2????

If Condition 1's value is equal to ??? and not the same as Condition 2,
and so forth ....

Return the new value for sum
