Issue Details

I am getting Error 84 indicating that there are too many format specifiers. What does this mean and how can I fix it?

Error 84 occurred at an unidentified location
Possible reason(s):
Too many format specifiers.


There are two reasons why Error 84 occurs. If you wired more format specifiers than parameters, it will cause Error 84. It should be one format specifier for each parameter. If you expend the input parameter and connect input more than 85 at once, it will cause Error 84. The input parameter of the Format Into String function is limited to 85. Instead of using over 85 parameters, you can use Format Into String function with the loop so that there is no need to use lots of parameters.
