Help with a text calculation

[aldipalo]

I thought this would be simple, but, it's driving me crazy!

Here's what I'm trying to do. I have a text field fk_UnitID that contains the following type data.

I-02F or II-04G or I-12A, etc. The I or II denotes the Building and the right side the apartment. I set up a calculation to get the Building from the UnitID:

Case(

Left(FK_UnitID;2) = "-";Left(FK_UnitID;1);

Left(FK_UnitID;2)

)

My problem is I get the II if the unit is II-02F

but get, I- if the unit is I-12A. I just want I.

What am I doing wrong?:

TIA

If the format is consistent, i.e. there's always a letter just before the hyphen and a numeric character immediately after, you can use:

LeftWords ( UnitID ; 1 )

Excellent. I tried Leftwords, but I was doing doing some fool thing wrong because it just wasn't working. Thanks for the quick reply.
