I tried what you suggested and that did not work either. actStatus will not be null. tal:define="actStatus result/Active_Inactive" returns either active or inactive and that is working correctly. This is what my python script looks like which includes a parameter, actStatus: if actStatus == 'active': return "#000" if actStatus == 'inactive': return "#b7b7b7" I have been working on this for two days straight and it has me stumped. Any help or suggestions would be great. Thanks, Laura Laura McCord wrote:

It seems like I have done this hundreds of times and it worked. Can some point out what I am doing wrong?

<div tal:define="actStatus result/Active_Inactive; colorStat python:here.statChk(actStatus)">

That seems correct to me. actStatus can be None?

I also tried this:

<div tal:define="colorStat python:here.statChk('${actStatus}')">

IIRC you should user statChk(string('${actStatus}')) or statChk(path('actStatus')) HTH --
