Hi iamdman:
John Doyle will provide you he real solution. From me in the following is a workaround ...

The image shows the variables laid out in the conventional vertical alignment in cells A1:A5 and the associated values in cells B1:B5.
I copied the variable names in cells A1:A5 and transposed them in cells A11:E11. For values, I entered the cell name B1 of the value of the variable A1 in cell A12, and then dragged B1 to the right to get the associated values B1, B2, B3, B4, and B5
in cell A13 I keyed in the formula ... =ODI(B1*B2*(B3-((B2*B1)/(1.7*B4*B5))))/UDI(1000000)
then in cell B13, I created the XLC equation for the formula in cell A13 ... then I moved the EQS function in cell B13 to cell A14, and I moved the graphic of the equation for fomula in cell A13 also to cell A14.
I could similarly create a formula in cell B13, and then move the associated EQS function from cell C13 to cell B14, and so on for mulas in cells C13, D13, and E13.
This workaround requires first keying in the variables first in the vertical orientation and then recreating them in the horizontal orientation. For this reason alone, this workaround may or may not work for you.
