[OpenFormula] Multiple Conditions in Report Designer

Hi,

is it possible to define a statement like

IF [VALUE] = X THEN BGCOLOR_1
ELSE IF [VALUE] > Y THEN BGCOLOR_2
ELSE [VALUE] < Z THEN BGCOLOR_3

within the Expression Editor (OpenFormula in Report Designer) ?

I could only figure out these standard definitions but they don't fit:

=IF([VALUE] < 0;"#FF0000";"#00CC00")

=IF(OR([VALUE] < 0;[VALUE] = 0);"#FF0000";"#00CC00")

Many thanks in advance.
