>I had an IIF statement in the dynamicBackcolor property of a grid that wasn't working correctly. So I started to try and figure out what was wrong and then realized I can't get the DynamicBackColor to work at all for me. I must be doing something wrong...I have ="rgb(255,0,0)". I've tried it with and without the quotes.

DynamicBackColor usually includes IIF function, e.g.:
**** Grid.Init event
cLine1="IIF(recno="+this.tag+",16711680,8421376)"
this.SetAll("DynamicBackColor",cLine1,"Column")
