This is my code in the combo "c21" init event:

This.AddProperty('aList[1]')
Dimension This.aList[5,3]
with This
.aList[1,1] = "2x4"
.aList[1,2] = 192
.aList[1,3] = .667
.aList[2,1] = "2x6"
.aList[2,2] = 128
.aList[2,3] = 1
.aList[3,1] = "2x8"
.aList[3,2] = 96
.aList[3,3] = 1.33
.aList[4,1] = "2x10"
.aList[4,2] = 80
.aList[4,3] = 1.67
.aList[5,1] = "2x12"
.aList[5,2] = 64
.aList[5,3] = 2
.RowSourceType = 5
.RowSource = "this.aList"
.ColumnCount = 3
.ColumnWidths = "50,0,0"
endwith

This is my coding in all involved combos interactivechange event:

ThisForm.lnCol2Value = ThisForm.c21.aList(This.ListItemID, 2)
ThisForm.lnCol3Value = ThisForm.c21.aList(This.ListItemID, 3)

&& BOARDFOOTAGE
Thisform.txt2.Value = val(thisform.c11.Displayvalue) * ThisForm.lnCol2Value * ThisForm.lnCol3Value * val(thisform.c31.Displayvalue)

&& LINEAL BOARDFEET
Thisform.txt2.Value = val(thisform.c11.Displayvalue) * ThisForm.lnCol3Value * val(thisform.c31.Displayvalue)

there are 3 combos, one with values 1-20, the second with the previously mentioned array, and the third with even numbers through 20.

if i select the 1st available value in each combo i should get 1*192*.667*2 which equals 256.128 (truncated to 256) for the boardfootage function. instead i get 1. for the lineal function, i get a big goose-egg.

i apologize for not posting enough information. that's a rookie for ya.

Thanks
