List Box Confusion

[ptc-2603810]

I am a first time MathCad user and have a project due for a grad class. I can not figure out how to use a simple list box to select a text string in the box and assign a numerical variable as the output. I have read everything in the Developer's Reference Manual but nothing is basic enough for me. Please help!

If you insert a listbox the default script does exactly that. Can you be more specific about what you don't understand, or are trying to do?

Thanks for responding! I would like to select a text string from the list box and assign a value to a variable. For example: if "stress relieved strand" is selected from the list box, I want to assign Yp=0.40; if "Low lax" is selected, I want to assign Yp=0.55.

You can have as many ElseIf statements as required.

Follwing is the script that I have been messing with for a week and still no luck! I truly appreciate your help.

Rem Initialize List Box
ListBox.ResetContent()

Rem Add Strings here as needed
ListBox.AddString("Bars")
ListBox.AddString("Stress Relived")
ListBox.AddString("Low Lax")


ListBox.ResetContent()

ListBox.CurSel = 0
Sub ListBoxEvent_Start()
End Sub

Sub ListBoxEvent_Exec(Inputs,Outputs)

If ListBox.Cursel = 0 Then
Output_number = .55
ElseIf ListBox.Cursel = 1 Then
Output_number = .4
Else
Output_number = .25
EndIf

Outputs(0).value = output_number
End Sub

Sub ListBox_Dblclick(1)
ListBox.Recalculate()
End Sub
