Stuck on syntax

What is wrong with this code?  All I'm trying to do is replace the field with a "0" if the calculated value is less than "0".


=IIf(([txtBalToMake]/[txtPatterns_On])<0,0,=Nz([txtBalToMake]/[txtPatterns_On],1))

Or this to avoid errors with nulls:


=IIf( NZ([txtBalToMake,0)/NZ(txtPatterns_On,1)<0,0, NZ([txtBalToMake,0)/NZ(txtPatterns_On,1))

One step further to avoid division by zero if txtPatterns_On is zero:

=IIf( NZ(txtBalToMake,0)/iif(NZ(txtPatterns_On,1) = 0, 1,NZ(txtPatterns_On,1) ) <0,0, NZ(txtBalToMake,0)/iif(NZ(txtPatterns_On,1) = 0, 1,NZ(txtPatterns_On,1) )

Missed a closing paren :-)

IIf( NZ(txtBalToMake,0)/iif(NZ(txtPatterns_On,1) = 0, 1,NZ(txtPatterns_On,1) ) <0,0, NZ(txtBalToMake,0)/iif(NZ(txtPatterns_On,1) = 0, 1,NZ(txtPatterns_On,1) ) )

Dale,

I'm on the East Coast too, but wake up insanely early.

What parameter is it asking for?

Double-check the spelling of the field name...

What I posted at http:#a38778340 is tested, and should work for you assuming that the textbox names are correct.

You might also want to check the fieldnames in the recordsource of your form or report and also the sorting/grouping if you are working with a report.

(Its possible that something other than this control source is causing that prompt.)

You might want to wrap all of the field names in brackets, but that should not be necessary.  I noticed that one of the earlier responses had a missing "]", but I believe mbizup dropped the brackets out of the latest version.

Also, if this is the control source for an unbound textbox, then I would probably go one step beyond  mbizup' last recommendation with:

=iif(NZ(txtPatterns_On,0) = 0, "Invalid Divisor", NZ(txtBalToMake,0)/txtPatterns_On)

This takes the NULL or Zero divisor totally out of the equation.

are you expecting to get a negative result ? cause - (negative values) are the only ones less than 0  (zero)




try

=IIf(([txtBalToMake]/[txtPatterns_On]) = null,0,Nz([txtBalToMake]/[txtPatterns_On],1))

I don't understand how converting a NULL or zero denominator  to a 1 solves anything.  It appears to me that it would be very misleading to your users.  Did you try:

=iif(NZ(txtPatterns_On,0) = 0, "Invalid Divisor", NZ(txtBalToMake,0)/txtPatterns_On)

This makes it very clear that the divisor is not valid for the computation, rather than assuming that it should be 1.
