HP Forums - INPUT command [allowed_types

Hi Friends,

I need to create an INPUT with ONE field that accept REALS (0 type) and too FUNCTIONS (8 type) so I used [ 0 , 8 ] as [allowed_types_matrix] ... this field only accept REALS (0 type) AND WITH 'X+5' GIVES "Error : Invalid input"

I created the following program for example (with 2 fields to not leave the form and test many times):

PHP Code:

EXPORT INPUTTEST
BEGIN
LOCAL fx, a;
fx:='SIN(X)'; a=0;
INPUT(
   {{fx,[0,8],{44,54,1}},{a,[0],{44,54,2}}},
    " INPUT TEST ",
   {"F(X):", "Real a :"},
   {"Enter F(X), could be constant, example = 5 ", "Enter a real value"},
   {'SIN(X)', 0})
END; 

Please Your help with any suggestion, thanks.

Best regards!!

Input is failing!
With {{fx,[8]} it should be enough, but currently it seems not to accept data if it does not contain any variable, clearly this is a bug.

Thanks Carlos.. I will use only type 8. And if the user needs to enter a REAL 5 would use '5+0' trick.
Have a great day.
