Hey guys, i was wondering if anyone could spend two seconds helping me out.
I keep getting this error when concatenating.
Conversion from string " and is an integer" to type 'Integer' is not valid.
This is the relevant line...
MsgBox("The number is " & NumInt, " and " & IntCheckF)
Cheers in advance, Steven.

Are you sure that is the relevant line? I don't see the string " and is an integer" in that line of code. Could you show a larger section of code? Or a screenshot of the error dialog

I think I see the error, in the line:
There is a comma after NumInt, I am guessing you accidentally put that there instead of an ampersand (&). The comma is splitting the code and the into two separate parameters of MsgBox(), instead of using them as one string.
Solution:
Replace the comma with the & operator
If you need any further help, PM me!
