Hooray!!! Success!!! After two days spent obsessing over the tech problem I have been having, it is solved. I had put a dash in the code when it should have been an underscore!
Unbelievable. Two days of my life wasted because of an erroneous dash.
The good news is that I can stop obsessing about computer code and clean the house before my children disappear beneath a pile of rubble. I might even get to my own Unplugged Project today too! Reminder: the theme this week is sculpture. Please join us!
