[amibroker] Re: Help required for correcting this code.

["Mike" <sfclimbers@xxxxxxxxx>]

Hi,

You've got two problems.

1) IIf returns arrays. So, both b and s will be arrays, not scalers. 
Therefore, you cannot use the 'if' statement with them later.

2) The operator '=' actually *assigns* a value to all elements of the 
array. For comparrisons, you must use the '==' operator, not '='. But 
again, since b and s are arrays, you cannot use this in an 'if' 
anyway.

Mike
