How to define a macro variable using equation with variables from dataset in SAS Miner

Question

I am trying to use &let in the beginning of my script to define a new macro variable... it should consist of equation from variables from dataset. The equation looks something like this, but SAS always gives me error like this (Runtime error was encountered, please see the log...).

The equation:

%let var_bad = (receivable_actual * 0.5) - 
               (EM_EVENTPROBABILITY * 0.02 * receivable_actual) + 
               ((1 - EM_EVENTPROBABILITY) * 0.5 * (receivable_actual - amt_instalment));

Can you guys help me fix it?

Thanks, Adam

@Jetzler: These are the errors it shows me in log.

ERROR 214-322: Variable name ( is not valid.

为什么不只计算数据集中的变量，然后将其选择为宏变量？
