Always need an item 1

[learningcurve]

I have this form code, written by another person.  Currently it looks to see if the first value($JECT) is empty.  If not it creates an itemcode1.  If it is empty, it skips to the next value($JCTL) and does the same, except it makes it itemcode2.  I need for the first one($JECT) to be itemcode1 if not empty, the second($JCTL) to be itemcode1 if the first is empty and itemcode2 if it is not.  The same for the third(LCJ) -item 1, 2, or 3 depending on the values of the others. So basically, I always need to have an itemcode1 for processing and possibly an itemcode2 or 3.  I hope this is clearer than it sounds to me. Thanks for any help!
