String manipulation (@left) in a sub-form

[deepbhasin]

String manipulation functions (eg @left) works alright in Lotus Notes views, but not in a sub-form.

Why is it that @left does not work in a sub-form & how can I get around it ?

The code used is "FIELD PRINT_ST := @If ((@Left(CB_REF_NO;1)="L"0;1);"

Thanks Deep

Prior to using the @left function, @IsValid function was used. This @IsValid function causes the problem. Wonder why ?

The code is as follows
@If(!@IsValid ;@Return(0);""
FIELD PRINT_ST := @If (@Left(CB_REF_NO ; 1) = "L" ; 0 ;1);
