try it this way

<td align="center" class="bottomLine" ><input style="border:0;<cfif
Len(pnum) IS 0> background-color:Yellow;</cfif>" type="text"
name="pnum#cnt#" value="#res.phone#" maxlength="13" size="10"></td>

I wonder if something like this isn't better handled by JavaScript.

If you user CF to set the textbox's color, then it only changes on pageload. For instance, it could be blank when the page loads initially, but then the user may enter something but the textbox's color won't change until the next pageload.

If, on the other hand, you use Javascript in the textbox's onChange event to evaluate the textbox's status (blank or not) and then update the textbox's color, then the color will change whenever the user edits the textbox.

What exactly do you mean by 'left blank'? When the form is loaded? When submit is clicked? After some validation? Please be more specific.

<cfif IsDefined("pnum")>
<cfif Len(pnum) IS 0>
<cfset bgcolor = "FFFFF">
</cfif>

</cfif>
Would this be correct or am i not using the right logic???

Ok so that would check the length of the string so to change the color

<cfif Len(pnum) IS 0>
<cfset pnum = "FFFFF">
</cfif>

Is that how it would work??? or am i missing something???
