I have a form that requires a part number to be entered. In my action page, i
query against a table using teh part number,
<cfquery name="qry" datasource=" db">
select partnumber from table
where partnumber = '#form.partNumber# '
</cfquery>

If no matches are found, qy.recordcount is 0, I use cflocation to redirect
back to the form with a javascript poppup message :
<cflocation url="form.cfm? showalert& comingfrom= actionpage" >

Back in the form, I check :
<cfif isDefined("showAlert ") and comingfrom is "actionpage" >
<script language = "javascript" >
alert('Part Number not found">
</script>

So if the part number enered is not found, I display a message back on the
form. Everything works ok except that as soon as the message is cleared (click
ok), it seems to come back when the form is reset or refresh and I get
complaints about that.

How can I eliminate the message once it apppears and the ok button is clicked.
I only want it to popup once and thats it. Also, somebody suggesed I use
showAlert but I have no idea what that does or means.

thanks
