Run Time Error 5 Invalid Procedure Call or Argument

[esong_98]

My program can't run because of run-time error '5' procedure call or argument. If I Google the term, I get websites that say that this type of error is caused by registry errors and you have to buy their product in order to fix it, is that true?

Also, before my program broke down, I ran some test runs which worked. I changed a value on my spreadsheet and that's when the error started to occur. The error was intermittent for the next dozen runs, but eventually all runs now have the error. Since there had been successful runs with the same code before, I suspect that my file may be corrupted.

The offending code is:

'Calculate Production function
Output_t1 = GrowthFactor ^ (Period_Length) * (Output_t0 + FactorProductivity * (1 - Damages_Production_t1) * _
(1 - AbatementCost_Production) * (CapitalStock_t1 - CapitalStock_t0) ^ Share_K_Capital * _
(Labor_t0 ^ Share_Labor))

Specifically, the program does not like the term CapitalStock_t1 - CapitalStock_t0. I've tested every variable and every combination of variables, and the program only dislikes the term above, although once in awhile I'll get another run time 5 error in another statement. But generally, if I have CapitalStock_t1 or just CapitalStock_t0 in the statement, the program runs.

If I use the term Output_t1 = CapitalStock_t1 - CapitalStock_t0 the program does not work. But it will work if I use Output_t1 = CapitalStock_t1 or Output_t1 = CapitalStock_t0. All combinations without the term CapitalStock_t1 - CapitalStock_t0 does work.


To give the offending code more context, its embedded in a double loop - which could be the cause of the problem (there are also a lot of other subroutines, but the double loop is all in the main subroutine)
