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)"> I also tried this: <div tal:define="colorStat python:here.statChk('${actStatus}')"> tried something like this too: <font color="" tal:attributes="color string:statChk{'${actStatus}')"> What is the correct syntax for this? It seems like I am really close but I am running out of ideas. Thanks.
