MQL5 EA stops working after adding new constant

[thatkyle]

After I have a working EA, when I:

• add a constant

• click update

• drag the newly added constant up to another position amongst the prior constants

• click update again

then, the EA no longer functions properly.

I have made no changes to any blocks and I haven't started using the new constant for any inputs.

Sometimes this is caused by spellings, "I think" words are used in behind the seen code, so using them causes conflicts. If this happens to me I will start the project from scratch, and/or change words.

Interesting. I was many blocks into a project but luckily had just saved a copy of the source so that I could revert. It took me a while to isolate the problem; what an annoyance!
