Hi, I have an excel sheet which contains cells with values, strings, and formula's. JMP imports the cells with values, strings, and simple formula's correctly. However, if the cell has a complicated formula (=SUBSTITUTE(MID(FORMULATEXT(Z29), 2, LEN(FORMULATEXT(Z29))-1),MID(FORMULATEXT(Z29),9,3),"x")) JMP replaces that cell with "#NAME?". It appears to not understand part of the formula, even though it works perfectly in Excel. Is there a way to correct the JMP import, without rewriting all of my XLS functions?
