Informix Error -2029

-2029 Screen record array name has component sizes which either

differ from the specified dimension of the array or differ among themselves.

The dimension of the screen array is written in square brackets that follow its name, as in the following example where the dimension is 12:

SCREEN RECORD details [12]

(items.item_num, items.item_desc, items.unit_price)

In this case, exactly 12 screen fields should be associated with each of the three columns that are listed in the screen record. This error message appears when one or more of the columns appear a different number of times.
