I have constructed a vlookup formula that looks up a date value from this sheet in an array on a separate work sheet and returns a time value in hours. I am accessing a number of cells on the sheet and am getting a #value error if any of them are blank. This is affecting other formulas in my workbook. Any ideas are very welcome! Thanks in advance!

PS Formula here: =VLOOKUP($A18,Shane!$A$3:$H$347,4,FALSE)+VLOOKUP($A19,Shane!$A$3:$H$347,4,FALSE)+VLOOKUP($A20,Shane!$A$3:$H$347,4,FALSE)+VLOOKUP($A21,Shane!$A$3:$H$347,4,FALSE)+VLOOKUP($A22,Shane!$A$3:$H$347,4,FALSE)
