Is it correct sentence?

ywrwea adyjd if values are too many

What does that mean?

if too many values

That still doesn't make sense. What are these values for/of?

for example, if I insert too many values in a program (It it became obvious from context)

We don't "throw" errors (at least, not in common English - maybe this is "IT jargon").

Maybe you mean something like "If you input too many values, the program will crash."

"IT jargon", yes,

But, I asked about "if values are too many"
It is grammar correct?
The reader knows what values are for.

"If values are too many" is not correct.

If there are too many values.
