Help on a function (or a program really)

I need to write a program which does an iterative calculation, but holed
over a value to use for an initial extimate. 
So far I have two functions and a table command. I think there should
suffice, but the program is not cooperating. COuld someone tell me where
I've gone wrong?

Clear[denr];
denR[c]:= (V:=v;
R=2*Pi*((G/(-(m*(V*c*p/Df)+-(V*(dH+cp*dT0))/(2*a*cp)))^.5));
{R}
)

Clear[Vel];
Vel[c]:=(R:=denR;
v= (4*Pi^2*Df*G)/(R^2*dT0*k);
{v})

S:=0.007
V:=0.01
hooks:=Table[Vel[c],{c,0.001,0.05,0.0001}]

All of the variables except V,v,R, and c are specified beforehand. I
have no idea why this is not working. Any help would be greatly
appreciated. I really don't want to have to dig out Pascal (the laguage,
not the dead mathematician ;) ).
