How do I combin multiple variables in RunWait

[sleepy]

I am changing a script to use variables rather than hard coded information. Most of the changed strings have work; except, where there are two variables.

So how do I fix this stirng.

$current = RunWait("file-check.au3.exe", $scriptpath, $count, "", @SW_MINIMIZE)

NOTE! If I replace $scriptpath with the real path it works. Yet $scriptpath is working in other code lines in same script. I have tried a number of

ampersigns with no luck.

Any pointers???

$current = RunWait("file-check.au3.exe " & $count, $scriptpath, @SW_MINIMIZE)
