The editor of a publication was having trouble with her computer.
So she called the computer guy over to her desk. He clicked a couple buttons and solved the problem.
As he was walking away she called after him, "So, what was wrong?"
And he replied, "It was an ID ten T error."
A puzzled expression ran right over her face. "An, ID ten T error?"
What's that in case I need to fix it again?"
He gave her a grin. "Haven't you ever seen an ID ten T error before?"
"No."
"Write it down," he said, "and I think you'll figure it out."
So, she wrote it down.........
