At best I'm teaching myself a little programming by hacking away building indicators, but basically, I'm stumble around trying different things till something works.

I have looked through google etc, and I don't understand why this statement doesn't work.... I must be missing something so basic none of the articles I have read have helped me figure out what is wrong, and why what looks perfectly logical to me just won't compile.

I want to execute a series of statements only if the current bar is within a certain range... this comes up alot when initializing indicators.... so in my ignorance, I write..

if ( CurrentBar >=5 & <=7 )
{
statement
}

Would some kind soul explain to me why that doesn't work, and what I should use instead?

Have you tried by simply repeating the variable name 'CurrentBar':

if ( CurrentBar >=5 & CurrentBar <=7 )
{
statement
}

Also, i think you need to double the & operator like this : &&

So your instructions should go like this:
if ( CurrentBar >=5 && CurrentBar <=7 )
{
statement
}

In short, you double everything as the computer is dumb and we need to repeat everything twice ;-)

It's more

 

Code

if ( CurrentBar>=5 && CurrentBar<=7 ) { statement }
