Boolean Statement Returning Incorrectly

Quote from jkov05

The z variable ranges over months and so Cells(2,z) tracks the years so, for example, after 12 years, Cells(2,149) + issueAge(0) should return > annuitizationAge(0) but it does not.
If I replace either issueAge or annAge with their values it returns correctly, but I need it to work for all X's.

Do you guys know why this is not working? Thanks!!

No where in your code snippet above, especially within the FOR loop have you changed the value of variable X. So X will only ever be the value that it is set to somewhere else in this procedure or maybe some other module. We also dont know if the function IssueAge or AnnAge are returning the correct value. We also dont know what X is supposed to represent. But for now, the value of X isnt being set or adjusted in your code snippet above, so it deifnitely wont work for "All X" as you claim you require.

Maybe post back the worksheet, with all the code, and an explanation of what the code needs to do in simple english

Desanitise your worksheet completely and your code.

If X is a period of time entered by the user (days or months or whatever), and if you argue that replace the issue age and annage function calls with actual values will fix the problem, then the problem in my head seems to be that you are not prompting the user often enough for new values of X, or the functions themselves are incorrect.

Its hard to debug when we dont have the full picture. Its like showing a corner of a painting to someone and asking them if they like the look of the entire thing

Looking now... sorry for the delay, I was out of town. Thanks for the sample... be right back

Its hard to say if this is the correct answer, because dont know what its supposed to be, but my guess is that you are getting a stream of zero's for "Annual GLWB Payout" where no zeros were expected

There are a few things wrong that I would suggest changing.

The arrays you defined are as follows (I dont know if this is the case in your real code, so forgive me if its unnecessary):
Dim issueAge(4), waitPeriod(4), annuitizationAge(4), deathAge(4) As String

This means that IssueAge, WaitPeriod, AnnuitzationAge are all arrays of type VARIANT. The final Array - DeathAge is an array of type STRING. My guess is you intended all arrays to be of type string. This is a common mistake made by new VBA'ers and it differs from say Java... where you could list a number of comma separated variables and a variable type.... not the case in VBA, you have to be explicit about each indiviual variable... for example
Dim x as string, y as string is OK, but Dim X, y as string means X is a variant and Y is a String...

(I Dont meant to be patronising when I say "new VBAers", but you'd be surprised the number of non-VBA "experienced" developers who dont realise or understand this behaviour).

Next, leading on from this, and more importantly, why would define a string array to store Integer or single values? I believe you should define them as:
Dim issueAge(4) as single, waitPeriod(4) as single, annuitizationAge(4) as single, deathAge(4) As single (or Integers if you wont be storing any decimal values)

However, doing this now means you have to typecast the values from the userform to ensure they are converted to actual values... e.g.
issueAge(2) = Val(exampleForm.tbIssueAge3.Value) this means that if it is a blank in tblIssueAge3 it wont "fit" into an array of single or integers, so you have to use the VAL(tblIssueAge3) which will return 0 for blanks, and this can be assigned to the array of type integer

Confused yet?
The simplest solution, leaving all the above aside, if you dont want to change any of your existing variable declarations - and go straight to something that works, then simply change the offending if statement and force the correct type casting. Because in here you currently have an array of strings, and you are trying to do comparisons against numerical data and VBA will not work as expected... so this line

If (Cells(2, z).Value + issueAge(x)) < annuitizationAge(x)

is evaluating to:
1+"60" < "71"

The " mark is indicate the value is a string.

So convert your string variables to numbers with the VAL function:

If (Cells(2, z).Value + Val(issueAge(x))) < Val(annuitizationAge(x)) Then

And it seems to work just fine.

Long story short - always use VAL when converting between string or variant types into integers/singles.
