how is findbitmap setup?

hey theres noone veiwing the help section so im posting this here. feel free to lock once awnsered. how should the findbitmap function be setup?

ive got this,

Code:

if (findbitmap(x,y,ammy,0,0,2000,2000)) then

but it says

Code:

Invalid number of parameters in script

witch means there arent enough. and should i put the hex code thing where ammy is?

Code:

if (findbitmap(x,y,BitmapFromString(33, 10, 'z78DA3330C007DCDC2C0D4C50' +
       'C8C10088770FA6CAC1E317625C825FCD60F0CBC8F4057E923CBDC' +
       '4BB8A5471CAE382987C442DD78EFA62D41723C117F84B0662DC00' +
       '0095C48E7A');,0,0,2000,2000)) then

or should it be something like this?

Code:

if (findbitmap(x,y,BitmapFromString(33, 10, 'z78DA3330C007DCDC2C0D4C50' +
       'C8C10088770FA6CAC1E317625C825FCD60F0CBC8F4057E923CBDC' +
       '4BB8A5471CAE382987C442DD78EFA62D41723C117F84B0662DC00' +
       '0095C48E7A'); then
