From a memscam I have a found address, memrec1 = 1041ebb4.
What i need to do is readSmallInteger(memrec1 +C). I believe that one just add C to the address, since it is a string. so some manipulations

The 'malformed number' error happens because of the way you are handling strings and hex prefixes in the immediate window or script.

In Cheat Engine Lua, readInteger or readSmallInteger functions prefer actual numbers (integers) as addresses.
You don't need to convert them back to strings or manually add '0x' before reading.

The Simple Way (Recommended)
You can do the math and the read operation in one line. Cheat Engine handles the hex notation 0xC automatically:

I knew it was a string but didn't realize that quotation marks needed to be added. To be clear when a memory scan finds an address: Lets say it was 1041ebb4 but that result is set to memrec1. To manipulate memscan1 I just used memscan without quotation marks why does this work awhile setting a param to 1041ebb4 failed?
BTW today when I firede up dosbox with wiz6 and ran my old recalculate without the second tier check of hp. A normal scan of memory found twelve addresses 12 addresses of the experience. At this game time all six heroes have identical experience. The recalculate set the first exp found along with gold to the first address found through the normal scan. Using the small bit of code you supplied at the end of the last post the hp was 89, correct and the second was also 89, so maybe different check would be in order, but the relearning comes first.
