ocean script if statement not workiing

Hi all,

I am new in the use of ocean script, but I would like to perform the following task: use ADE assembler calculator cross() function on a signal, but when a certain design variable A has value 0, then the cross() function should return 0 (rather than nil, 0*nil would still evaluate to nil, so I cannot just multiply them).

I thought to approach this by an IF statement, I tried to look at an ocean documentation, so I created a file called myFile.ocn, loaded it in the outputs setup and its content is:

if (VAR("A")==0 0 cross(vtime('tran "/mySignal") (0.5 * VAR("vsupply")) 1 "rising" nil nil nil))

But that returns eval err. In the ocean reference it is stated that:

"if if( g_condition g_thenExpression [g_elseExpression] ) => g_result Description Evaluates g_condition, typically a relational expression, and runs g_thenExpression if the condition is true (that is, its value is non-nil); otherwise, runs g_elseExpression. The value returned by if is the value of the corresponding expression evaluated.

What am I doing wrong? ADE shows an eval err (it is the case even when I replace the cross() function from the IF with just a number)

Thank you very much

Best regards
