When Creating a New Measure I can no longer reference table column header names, only measures

[odanovich]

I was building a lot of measures in my data model and then suddenly I am unable to refernce table column header names... they wont pop up to use in the formula!  I can only reference other measures..  I've been working with PowerPivot since the PowerPivot 2010 Add-On.... What is in the world is going on here?!?    I am unable to make any progress because base measures rely on the ability to reference column headers!   wholy cow am I frustrated..   some one please come to my rescue and fast!  I am a contractor and I have made promises to complete this project within my deadline!  At this time I am complete stuck.

If the column header names wont pop up in the formula, how about the result if you type the column names directly in it? Will there be expression error? Could you please also post a screenshot for this issue?
