in my personal.xls file i have a module Financial in financial i have a function Interpolate in my xl file i would like to wright in cell a1 =Interpolate(b1,b2,c1,c2,c3)

this will work when interpolate is in module1 of the book i am in at the time (book1.xls) but when i put the function into my personal workbook in module financial it no longer works

what i did was use the fx (function wiz) near the formula bar, then i selected user defined from the cat cbo and it showed how to ref my func
