There must be exactly one space character on each side of a binary operator such as = + - AND OR =. The parameter comma operator however, should have no spaces.

```al
"Line Discount %" := "Line Discount Amount"/"Line Value"*100

```

```al
StartDate := CALCDATE('<+'+FORMAT(Days + i)+'D>', StartDate);  
```

StartDate := CALCDATE('<+' + FORMAT(Days + i) + 'D>',StartDate);  
```
