how to use javascript in Datalist Question?

[Guest]

I have a href link in a Datalist

<a href="addtocart.aspx" onmouseover="void
validateNumericField(document.Form1.txtphone);" onkeyup="jump();" >

I'm trying to validate a TextBox with Id ="txtphone" as above
The TextBox is also in a Datalist.

I have declared the textbox in the OnItemDataBound of the DataList like so:-
Dim txt As TextBox = CType(e.Item.FindControl("txtphone"), TextBox)

But my Javascript isn't firing it seems its not seeing the right ID's

Any Ideas what 'm doing wrong?





But ites not working?
