PATTERN is driving me crazy, pls. suggest me good syntax

Question

Hello
Bcz of i placed PATTERN under DISPLAY tab, am getting errosrs like "Integer has too many digits", "Empty is too long"...I am guessing these are all bcz of some SPACES on these value fields, but not sure from where these spaces are coming? may be user entered some value and just moved the cursor/space bar right hand side, not sure, how to truncate space in BINDING tab's pattern?
I have 12 value fields in my form, they are for quantities, volumes, price, amounts. I put them as Decimal fields and each field has its own length, as mentioned below
1) Volume field - Decimal field - Limit leading digits as 15 and Limit trailing digits as 3
I put the Pattern only on Display tab as below (I didn't put any pattern any other tab, like Binding, Edit, Valiodation tabs)
By selecting the num.integer on SELECT TYPE left side, I put as below
null{}|zero{}|num.integer{}
(Checked Allow Empty, Allow Zeros check boxes)
Pls. help me by telling What is the correct syntax i need to put here?
Do i need to put pattern also any other tab, like under BINDING tab, if so, psl. let me know the syntax?
By selecting the num.decimal on SELECT TYPE left side, I put as below
null{}|zero{}|num.decimal{}
(Checked Allow Empty, Allow Zeros check boxes)

Answer 1

Thank you.
Pls. let me know
1) My understading from your answer is, i need NOT to put any PATTERN in BINDING tab? am i correct?
2) Sure, i will put the suggested below syntax, but pls. let me know do i need to select any entry from the left side box (as shown in the black box in below screen shot?) and then i put the suggested below syntax/patern? or i don't need to select any entry from the left box as shwon in below screen shot as black box?
null{'Enter a Number'}|num{zzz,zzz,zzz,zzz,zz9.999}
3) For example, if i select num.deciaml {} option.....then the blue high lighted part is coming as trail part to the syntax? is it OK, let it come?
4) So, i guess, for 2 leading and 2 training length, i need to put below pattern, am i correct?
null{}|num{z9.99}
Edit pattern would be for 2,2 is as below, am i correct?
null{}|num{z9.888}
5) Do i need to check the ALLOW EMPTY and ALLOW ZERO check boxes? or not?
6) By chance, if user put spaces, then I want to truncate spaces / delete the spaces in the middle of data or anywhere in the data/field, so can i use as below? if not, pls. suggest me for get rid off spaces from anywhere in the field, bcz i am guessing these crap spaces is causing an issues for me
null{'No data'}|num{zzz,zzz,zzz,zzz,zz9.999}
Thank you
