I suspect the unit mismatches are due to an incorrect implementation of the labels used in Prime during the worksheet conversion. For example, if you look at the last line of the Morphologic Time Loop program some of the variables have units removed by the normal division operator, and some by the inline division operator. When the inline division operator is used the units are not labeled as units.
The error with U1() seems not to be due to units but you are right, that will not be the only error. I didn't scroll far enough to the right to spot that labelling discrepancy. Its not an easy to debug worksheet, indeed.
