if statement - Condition IF in Crystal Reports -

OK, this time it's a simple question!

I have ordered two field db> q and given the deliverance.

If my customers order their goods through us, but the supplier protects their belongings then the quotation given to the invoice will be = 0.

Now I have a filter that if the quantity distributed is 0, then it is ordered to set = = qty.

Now things get a little confused .. Two different types or orders use the same template, which is the order

So this is what I am trying to do. ...

If ORDER.TYPE = 'SOI' then ORDERQ.DLVQTY = ORDERQ.QTY

I am putting it on this field's formula but nothing changes on the report He Came?!

Any thoughts? Does this make sense ?!

I am confused ...

I think this is the same

  If ({ORDERQ.DLVQTY} = 0) then {ORDERQ.QTY} is another {formula} other { ORDERQ.DLVQTY};  

Then place the original {QtyDelivered} field in your report instead of that original format field.
